Heated Seats don’t work — Chevrolet

Every automobile manufacturer has their unique system for controlling the heated seats in their vehicles. The technique I’ll explain here is designed to solve the problem of many Chevrolet heated seats not working. This applies to all General Motors cars, including Buick, Cadillac, GMC, and Pontiac.

Heated Seat Components

Driver and passenger side heated seat control switches are included in the GM heated seat systems for vehicles manufactured from early 2000 through the end of 2000. Seat back heating elements on both the driver’s and passenger’s sides The heating elements for the driver’s and passenger’s side seat cushions Seat back temperature sensors on both the driver’s and passenger’s sides Module for the driver’s seat Module for controlling the driver’s door Control module for the passenger door Module for the passenger seat

How Chevrolet heated seats work

The system was built by General Motors to have two heat zones with three heat settings. The warmers in the seat cushion and the seat back are controlled via the controls on the steering wheel.

Pressing the seat cushion button causes the warmers in both the seat cushion and the seat back to be turned on by the driver. If the driver, on the other hand, hits the seat back button, just the seat back heating will be turned on.

Three heated seat heating levels

Number of times the seat cushion and back or back buttons are pressed determines the quantity of heat produced. When you press the seat cushion 1 time, the seat back and cushion heating elements are activated and run in the high heat mode, as well. Further strokes of the same button lower the heat level from high to medium, then from medium to low, then from low to off. The similar procedure applies to the seat back button; the initial push raises the heat level, while further presses lower the temperature.

How buttons control heated seats

It is powered by a door circuit breaker (25A) and a driver/passenger door module fuse (15A) installed in the left instrument panel fuse box to supply battery power to the door modules. The door modules then deliver electricity to each heated seat switch, with each button push resulting in a transient contact closure on the contact closure circuit. The contact closure requesting heat and heat level is detected by the door module, which conveys the request to the seat module through a digital bus system.

  1. The wiring diagram for the other seat is the same as the one for the first.
  2. The seat module is responsible for supplying power and ground to the seat and back heating elements of the vehicle.
  3. Additionally, the seat module regulates the heat level by turning on or off the ground, in addition to determining which heating element is engaged.
  4. It is the seat module that provides the 5-volt reference to the thermistor, and it is this module that records the voltage drop from each thermistor as a function of the temperature that it perceives.

(2)Check for battery power at the door module (3)Check for good ground at the seat module (4)Check for good ground at the door module (5)Check for power at the rear switch (6) Check for power at the back of the chair and the seat switch (7) Disconnect the electrical connections that link the seat module to the heating elements and perform a test. Continuity of the seat thermistor (set meter to ohms scale). At normal temperature, the resistance should be between 10K and 2K. If the meter displays OL or, this indicates that the seat thermistor is open and must be replaced.

Set the ohms reading on the meter.

It is necessary to replace the element if the meter displays OL or a minus sign.

When the seat warmer is turned on, check to see whether the light turns on even with the bulb in place.

If the light does not come on presently, the element must be changed. The year 2020 is a leap year. Rick Muscoplat is a professional musician. Rick Muscoplat posted a blog entry on

What’s the Downside of Heated Seats

When automobiles were initially introduced, riding in them might be quite uncomfortable, especially during the cold months. After all, because these early-model automobiles had open bodies, the wind could whip about drivers and passengers alike while rain, snow, and/or sleet pelted them from all directions on a constant basis.

Glass windshields first appeared in 1907, reducing the amount of wind that hit the automobile, and people wrapped up and put gas lights in their cars to provide some radiated heat, but the weather remained very cold. Getty Images is the source of this image.

A history of heat in cars

The Hudson ‘Twenty,’ which was manufactured in Detroit beginning on July 3, 1909, made its premiere at the 13th National Automobile Show in New York. It was the first mass-produced automobile to be totally enclosed, and it was shown during the show. Because this vehicle provided a more comfortable ride, 4,000 units were sold that year, despite the fact that it cost approximately $1,000 to purchase (about 26,000 dollars today). It’s important to remember that vehicle financing wasn’t commonly offered to purchasers back then.

  1. Hudson was the third largest automobile manufacturer in the United States, behind Ford and Chevrolet, by 1925.
  2. Several enterprising individuals attempted to recycle exhaust fumes into their automobiles in order to reap the benefits of modest quantities of interior heat.
  3. Despite the fact that it took a long time to get going and that the engine-generated heat was uneven, it was far safer than breathing exhaust fumes.
  4. The first contemporary heater core was introduced by General Motors in 1930, right in the thick of Ford’s inventions.
  5. Despite the fact that advances in the automobile industry, including heaters, are always being developed, this 1930 model remains the foundation of what is currently in use.

Heated car seats: the history

The use of automotive warmers makes driving significantly more comfortable, but a heated car seat would deliver focused heat to a specific body region, which is an appealing concept to many. It has been stated in several places on the internet that General Motors (GM) tested automobile seat warmers on certain models as early as 1939, but no more information or sources have been found to support this claim. Because Robert Ballard of General Motors is credited with the initial patent for heated seats, the company was a pioneer in the heated seat initiative.

See his patent for more information, including photographs and a full text.

This solution looked more like heating pads for the seats than the more complex alternatives available today, but at the very least they were warm.

After all, according to Saab, their first objective was to reduce back pain, which would result in more joyful travel and safer driving.

Heated car seats: the drawbacks

According to a 2011 article in The Legal Examiner, heated seats are standard equipment in around 30% of all automobiles on the road today. Edmunds.com puts it another way, saying that roughly 300 distinct automobile models are equipped with seat warmers. There is no doubt that they are a source of warmth throughout the winter months. However, despite the fact that manufacturers normally state that these heaters have a maximum temperature between 86 and 113 degrees Fahrenheit, temperatures have been known to surpass 150 degrees.

  1. The capacity to detect danger in time to turn off the heating in drivers with diabetes, neuropathy, and/or other paralysis difficulties may be impaired in these individuals.
  2. Continuing with the story, it is said that both the National Highway Traffic Safety Administration and the Society of Automotive Engineers have organized ‘what can only be described as crack teams’ in order to get to the bottom of the situation and establish safety guidelines.
  3. In accordance with the article in The Legal Examiner, the integrity of the burnt skin might be irreversibly affected.
  4. What’s the bottom line?

Are Heated Seats Bad for You?

When it’s freezing outside, there’s nothing nicer than snuggling into a heated seat in your automobile. Is it, however, potentially hazardous? Cars have gone a long way in recent years, but there are still certain aspects that might be improved, and heated seats are one of those places. In fact, several experts are concerned that excessive usage may result in burns. And one motorist found out the hard way about it.

How do heated seats work?

‘The following attributes are allowed: src=’ frameborder=’0′ allow=’accelerometer, autoplay, clipboard-write, encrypted-media, gyroscope, picture-in-picture; src=’ frameborder=’0′ ‘allowfullscreen=’ allows you to use the entire screen ‘> The following is an example of a formalized formalized formalized Despite the fact that heated seats appear to operate by magic, their inner workings aren’t all that difficult.

According to Bockman’s Auto Care, this is the same technology that is used in heated blankets, hair dryers, and water heaters.

When electricity passes through the coils, the resistor acts as a barrier between the electricity and the coils, generating heat in the process.

A thermostat built into the seat is intended to keep track of the current temperature.

But the difficulty is that some manufacturers do not include a thermostat that automatically shuts off the heat, thus it is up to the tenant to turn off the heat if the temperature rises to an uncomfortable level.

Too much of a good thing

Even while heated seats are quite convenient, it is easy to misuse them. The bad news is that you might not even realize you’re doing it until you’ve been burnt by your actions. ‘Erythema ab igne,’ which is Latin for ‘redness from fire,’ is said to be caused by the frequent usage of heated chairs, according to WTOP News. The term ‘toasted skin syndrome’ (also known as ‘TSS’) is used by clinicians to refer to this condition. So, exactly, what is this thing? When the skin on your back of your thighs gets discolored due to extended usage of heated chairs, you have what is known as ‘hot seat syndrome.’ ‘The key here is repeated exposure, with effects manifesting themselves over weeks and months of use,’ according to WTOP News.

The disadvantage of TSS is that it is difficult to detect.

The symptoms might appear gradually, and by the time the skin begins to ache enough for you to notice, there has already been major damage done to it.

One man’s heated seat gave him third-degree burns

Despite the fact that heated chairs are quite convenient, they may be deadly, as one guy discovered. An injured motorist was found with third-degree burns on his upper legs and second-degree burns on his lower legs after a road trip from Missouri to Louisiana ended in disaster. Despite the fact that he was paralyzed and had no sensation in his legs, he had mistakenly turned on the heated seats in his automobile and didn’t notice the burning. He allegedly endured ‘immense physical agony and mental misery’ during his recuperation, which lasted many months.

  • The heated seats in the Chevrolet Silverado pickup truck he was driving did not have an automated shutdown, which would have turned them off when the temperature reached a specific level.
  • General Motors is being sued by the driver for neglecting to provide a shutdown switch in the vehicle.
  • There have been several reports of this happening, and it is now suggested that anybody who has paralysis in their legs refrain from using heated chairs.
  • It’s natural to assume that automobiles will be outfitted with it, but that may not be the case.

Follow these procedures to diagnose and repair a heated vehicle seat that is not heating up correctly.

Is the heated seat not functioning? Here is where you can schedule a service appointment. It’s possible that your heated seat isn’t functioning properly due to a blown fuse or misplaced thermistor; however, this isn’t always the case. Photo:pxhere


The plug might be a contributing reason to a faulty heated seat. The plug is normally found under the seat, where it connects to the vehicle’s electrical system. When inspecting the plug, look for any corrosion or dirt in the sockets of the connectors. Check to see whether the plug has electricity by turning on the car’s ignition and seeing if the plug has power. Check the voltage on both sides of the switch using an electrical tester to ensure that both sides have at least 12 volts.


The failure of a fuse is another typical cause of a heated seat that is no longer operating properly. Look through your owner’s handbook if you are unsure where the fuse box is situated in your vehicle. Examine the fuse box and replace any blown fuses that you may uncover while doing so. One of the simplest and most straightforward methods of repairing a faulty heated seat is to replace a blown fuse. Convenient Add-ons: Upgrade the comfort and convenience of your drives with these new General Motors accessories.


Heated seat pads are a convenient option if your vehicle does not come equipped with built-in heated seats. Photo courtesy of AmazonNext, locate and examine the thermistor, which is the device that keeps the heated seat at the proper temperature. Using care, carefully remove the seat cover in order to locate the thermistor. Take note of any scorched patches on the seat or on the carpet of the vehicle, which might suggest that the thermistor has been relocated. If the thermistor is not installed in the proper location in the seat, it will be unable to detect the proper temperature.

Heating element

If the plug, fuse, and thermistor all appear to be in good working order, it’s time to check the heating element in the seat itself. A heated seat that isn’t operating properly is frequently caused by the heating element, simply because the heating wire that warms the seat is fragile and prone to breaking. To determine which portion of the heating element is malfunctioning, use an electrical tester to conduct a test. A partly or completely broken heating element will almost certainly necessitate the replacement of an entirely new unit.

Aftermarket Heated Seats

There are undoubtedly a slew of them available, but I would recommend taking a look at Check Corporation. This firm manufactures seat warmers that are on par with, if not better than, OEM quality. This product has met or surpassed my expectations, and I am pleased with the company’s website.’ They’re clearly constructed from high-quality materials, and the installer had nothing but positive things to say about them. I had first gone to another installer who seemed to be solely concerned with getting it done quickly and with getting me in and out as quickly as they possibly could.

If that’s all that matters to them, they’re not going to bother with anything else than anything inexpensive!

I realize that the most majority of seat heaters are mass produced in China, but I think that the Check Corporation seat heater is manufactured in the United States. Please double-check this with me because I am not certain of what I said. I hope this has been of assistance!
