2001 Toyota Camry XLE seat heaters don't work

My seat heaters don't work. The switch lights up when pushed but no heat. Is it the elements in each seat or something else?

    It is unfortunate if it is the heater elements. That is the second time the passenger side has gone. The first one was under warranty. They are very expensive and I don't like the prospect of removing the leather seat cover to expose them. I also seems pointless to change them if they are just going to break again. I just hoped it was something else like an easily swapped relay.

    Thanks Toyota Ed.

    If the switch lights up, the relay and the power sources can be construed to be OK. If the heaters are not unplugged, and the wires are OK, the only possibility is the heater-elements. Sorry.

    You most likely have an open circuit in the heaters themselves. The heaters are nothing more than an element that resembles the rear window defroster grid.

It can be done, but for the cost of a new heating element, it is worth the purchase. The replacement for my 2001 I think was ~ 40.00 ( online, plus shipping costs ) for the bottom cushion heating element.

You can take the same amount of work to remove the seat cushion, remove the cover, and try soldering the broken elements ( usually the thigh area in the front ), but you have a used element that is patched. The way I have seen it done, is actually using wire to close the circuit again, not create a new element section.
The seat bottom work is a bit much ( to make sure the cover is on straight and no creases ) to spend the time patching vs. replacing what is a fairly cheap part.
You can try Tasca and Southwest ford parts online for the current element pricing.
Depending on the shape of the cover and cushion itself, you might consider replacing those ( or the cushion ) as long as you have it apart, but this is getting a bit expensive ( would be ~ 200.00 for all 3 new ).
I did the cushion at the same time, and it made the world of difference to the feel of the seat, just like the day it came out of the factory.

Check the ground cable going from the battery to
alternator, then to chassis. Make sure there is no
rust at the chassis ground wire terminal, and that it
is very tight. The fusible link will be off the alternator
red power cable,usually, but not 100% on that car.
Good luck.

Heated seats do not work


First off, I would contact your local Jeep dealer and have them run your VIN # to check for any recalls. The 1999-2004 Grand Cherokees had a recall on the seat heaters. If your vehicle doesn't fall into the VIN # range then either your seat heater switch has gone out, or you have a broken element in the seat heater. I have replaced more seat heaters than switchsm the elements heat up and break. Hope this helps out.

Best of luck

Drivers seat heater will not switch on. New fuse installed.


the switch works the relay, the relay powers the heater, being a 12volt heating element, it's bound to have a good size wire going to it, make sure the wire feeding that relay is hot, it will be a larger inline fuse or a fusable link,it will come off a main power source,I.E. the starter or something like that, the small fuse you replaced is for the relay curcuit,good luck

Bottom portion of passenger heated seat not working, but the back heated cushion is working normally. The lights for the seat warmers in both activation switches are illuminated when selected.


It sounds like the heating element is broken. Unfortunately they don't usually tell you that if you have heated seats, kneeling or stepping on them, even briefly (as if you were leaning in to get something from the car), or putting something heavy with a firm edge (like a heavy box), can sometimes break one or more of the wires in the heating element. I'd be willing to bet that this is what has happened. The heating elements in the seat are wired together, so it's not a case of having a heat control module for the cushion dying while the one for the backrest is OK. If the whole seat stopped heating, I'd think about looking into the controls for the seat, but with part of it still working, it's likely that the cushion heater has been damaged and will have to be repaired or replaced.

The driver seat heater just quit. all fuses are good. how do you tell if the relay is good?


Swap it with a relay you know to be good and see if it works again,pick a relay that is not important to the function of your car.

Heated leather seats will not heat up. Switch lights up and all fuses are okay. Is there a hiddedn relay I am not finding? Is there a quick way to determine if the problem is in the heating element under...


are you saying neither the heated seat cushion nor heated seated back on either seat works? But the light or lights does work?

Please rate as solved if this helps you. It took some time to dig all this stuff up. Please report progress.

Here's some info to start you off:

  • The heated seat is inoperative — seat does not heat but the heated seat switch illuminates when pressed
  • Circuitry.
  • Heated seat module.
  • Seat heater and temperature sensor.
  • Seat back heater.
  • Heated seat switch.

2002 Grand Cherokee Heated Seats don't work


I will post it in 2 different posts because its too long DB

HEATED SEAT SYSTEM
Individually controlled driver and passenger side electrically heated front seats are available factoryinstalled optional equipment on this model, when it is also equipped with the power seat option. The heated seat system allows both the driver and the front seat passenger the option to select one of two seat heating ranges, Low or High, or to turn the individual seat heaters OFF using the heated seat switches located in the center lower bezel near the bottom of the instrument panel center stack. The heated seat switch circuit operates on ignition switched battery current supplied through a fuse in the junction block, only when the ignition switch is in the ON position.

The heated seat system consists of the following components
  • Heated seat elements
  • Heated seat sensors
  • Heated seat module (or memory heated seat module)
  • Heated seat switches.
The heated seat system also relies upon resources shared with other electronic modules in the vehicle over the Programmable Communications Interface (PCI) data bus network. The PCI data bus network allows the sharing of sensor information. This helps to reduce wire harness complexity, internal controller hardware, and component sensor current loads. At the same time, this system provides increased reliability enhanced diagnostics, and allows the addition of many new feature capabilities. For diagnosis of these electronic modules or of the PCI data bus network, the use of a DRB scan tool and the proper Diagnostic Procedures are recommended.

The electronic modules that may affect heated seat system operation are as follows:
  • Body Control Module (BCM) - Refer to Body Control Module in Electronic Control Modules for more information.
  • Heated Seat Module (HSM) - Refer to Heated Seat Module in Electronic Control Modules for more information.
  • Memory Heated Seat Module (MHSM) - If the vehicle is equipped with the Memory System, refer to Memory Seat Module in Electronic Control Modules for more information.
Refer to Power Seats Premium I/III in the Contents of Wiring Diagrams for complete circuit diagrams. Following are general descriptions of the major components in the heated seat system.

The heated seat system will only operate when the ignition switch is in the ON position, and the surface temperature at the front seat heating element sensors is below the designed temperature set points of the system. The heated seat system will not operate in ambient temperatures greater than about 41 °C (105 °F) . The front seat heating elements and sensors are hard wired to the Heated Seat Module (HSM) or the Memory Heated Seat Module (MHSM).

The heated seat switches are hard wired to the Body Control Module (BCM). The BCM monitors the heated seat switch inputs, then sends heated seat switch status messages to the HSM or MHSM over the Programmable Communications Interface (PCI) data bus. The HSM or MHSM contains the control logic for the heated seat system. The HSM or MHSM responds to the heated seat switch status messages, ignition switch status messages, and the front seat heating element sensor inputs by controlling the output to the front seat heating elements through integral solid-state relays.

When a seat heater is turned ON, the sensor located on the seat cushion electric heater element provides the HSM or MHSM with an input indicating the surface temperature of the seat cushion. If the surface temperature input is below the temperature set point for the selected Low or High heated seat switch position, the HSM or MHSM energizes the integral solid-state relay, which supplies battery current to the heating elements in the seat cushion and back. When the sensor input indicates the correct temperature set point has been achieved, the HSM or MHSM de-energizes the solid-state relay. The HSM or MHSM will continue to cycle the solid-state relay as needed to maintain the temperature set point.

The HSM or MHSM and the seat heater elements operate on non-switched battery current supplied through the power seat circuit breaker in the junction block. However, the HSM or MHSM will automatically turn OFF the heating elements if it detects an open or short in the sensor circuit, a short or open in the heating element circuit causing an excessive current draw, or when the ignition switch is turned to the OFF position.

See the owner's manual in the vehicle glove box for more information on the features, use and operation of the heated seat system.

A common cause for the heated seats to not work is a burned heater element. There is an element under the seat cushion cover, and one under the seatback cover. If either has failed, both will not work.

VW Cabrio 2002 heated seats


If the fuse isn't blown, it may be a broken heating element or a disconnected harness. Look under the seat and take a look at the wire harnesses - are they all plugged in? Jiggle or push on them a bit (do NOT do this to any yellow connectors under there though - yellow connectors are for airbags and the static electricity in your body can blow them). If they're all OK, and that doesn't work, and no wires are broken in the connectors, you may have a damaged heater. Has anyone ever knelt on the seat to reach across and get something? That kind of excess pressure can easily damage the heating element.

Could be that the wiring for the heater is broken, or that the heating element itself has been damaged. Has anyone knelt on the seat when reaching in to get something out of the car? Or has anyone stood on it (a child maybe)? Pressure like that can break the heaters and keep them from firing up.
