SOURCE: both front heated seats not working

Could be a broken wire on the bottom of the seats, the wires become hard over the years and the movement of the seat moving back and forth can cause the breakage.
It could also be the thermostats that are fitted into the base of the seats.

That is the power distribution center, the fuse box is under the dash to the left of the steering column under a cover, they are marked, the plastic cover will have FUSES molded into it.

There are seperate blowers for the front and rear air. It is most likely either your blower motor or the resistor, both located under the passenger side dash. I got a blower from a salvage yard for $25, But ended up having to get the resister from the dealership for about $130. Hope this helps.

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.

The heated seats stopped working.


It could be a fuse or possibly a burnt element altho Ive never really heard of one doing it on both sides at once when it was an element.There is a reset button on some under the hood on the drivers side I believe.

My driver side heated seat has quit working.But passanger side still works.Is there a fuse i can check for this.Thanks 2001 chevy impala


more than likely it is the heating element in the seat that went bad. if there is a light on the switch it should be getting power and the heating elements under the seat coushin do go bad. it is not an uncommon thing.

The drivers heated front seat, does not work?


Check under the seat to ensure the plug has not be dislodged from its socket, check fuses in fuse box, if this fails it will either be a relay, switch or the actual seat element. Hope this helps

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 seats not working on 2002 Oldsmobile aurora


Hi


Thanks for using FixYa. Check for a broken wire connecting the heating element. 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. Take the seat apart and investigate the problem thoroughly.

Determine if the front seat assembly heat element resistance values are within the specified range.
If the resistance values are NOT within the specified range, install a Front Seat Heater Package between the existing front seat trim cover factory heat elements and the seat cushion and back foam pads.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

2002 Chevy Impala driver's heated seat does not work


I would imagine that if you only felt the extreme heat in two specific spots on the seat, the element may have burned out and you basically have an open curcuit. According to the wiring scematic, the elements in the back rest and the seat itself are connected so neither work now. I've tried removing the leather from my seats to figure out if I can just replace the elements, but the elements are molded into the foam in the seat. Your only solution may be to replace the entire seat or to buy a ******** seat warmer. Most of these ******** heat warmers are rather cheaply made, though.

Passenger seat heater not working in my 2003 volkswagen jetta


There should be a connector under each seat which connects power to the heating element. It is likely either clipped to the seat or tucked under the carpeting. You'll almost definitely need to remove the seat to get easier access to it, though it should be possible to find/access it without removing it, just more difficult. Once you find it, disconnect it. You can use any multimeter with a continuity tester to test the circuit. First, check the DC voltage coming from the wires that come up from the floorboard. If you are getting voltage there, you will want to check continuity of the element itself by probing the two wires with the meter set to it's continuity testing selection. If there are more than two wires you will need to determine which is the common wire and which are the "live" wires. With the power disconnected you can test the element to figure this out easily. For example if your heated seat has three wires, test all three for continuity in pairs. If one wire always shows continuity no matter which other wires on the same plug you touch that should be common.

If the element tests good (in other words you find that all the circuits show continuity) and you are getting power from the plug that comes from the vehicle itself, you might need to check the resistance of the element. It is rare to have a bad element that still shows continuity, but it is possible that the resistance may have for some reason become lowered and the element therefore does not heat up.

Try these and let me know how it goes!

Heated seats


Likely, the heating element in the seat has failed. The reason is simply that the drivers seat is in use more than any other seat in the vehicle. You can check continuity of the element with an ohmeter across the seat side of the heater connector. Check for power at the harness side with a volt meter. If there is power but no continuity, heater element has failed. Personally, I'd probably just live with it but you can either attempt to install a new heater element or if you can find a similar seat in a salvage yard, just buy it and put it in! (whole seat probably costs less than the element!!!

Heated seats don't work


See GM TSB 05-08-143-001, If you have Adjustable pedals, especially if they don't work with the memeory buttons, but function with thier own buttons. Its the Brake Pedal Position Sensor is shorted and mesing up the seat module which controls the heaters too. My 05 Suburban had the same issue. Can check by unplugging switch and see if heated seats work .
