SOURCE: I'm not sure how to turn heated seats on in my 2002 gmc envoy.... do i even have heated seats.

If your vehicle is equipped with heated seat, there should be a control button on the door where the window buttons are.

The drivers seat won't move and the heated seats won't work on both sides. Where is the fuse?


Check underneath the seat for an inline fuse. It is a glass type fuse in a fuse holder that you have to push and twist to get out.-----------------------------------------------------------------------------

Why won't the heated seats work


Check fuse for seats.

Check switches for seats, replace if necessary.

Check wiring to seats and make sure connections are good.

2002 Trailblazer heated seats won't work


First check circuit breaker #8 and fuse #19 in the rear fuse panel. If these are OK, you will have to troubleshoot the seat heaters themselves (loose connector, broken wires, defective heater coil, etc.)

The driver's side heated seat won't turn off on my 2003 Mecury Moutaineer. Also, how do I change my cabin filter?


Your vhicle build date is on a blue sticker on the driver door or door frame. If not there, check other doors.
The heated seat Module is under the seat. You can unplug the connector on it or the heated seat switch to shut it off. I supect the module is bad. get one used from car-parts.com. The cabin air filter is under the leaf screen at the base of the windshield. Remove wiper arms and leaf screen for access. Please rate, thanks. Principles of Operation - Heated Seats - Vehicles Built 03/2002 Onward
NOTE: Two heated seat modules are used, one for vehicles built up to 03/2002 and one for vehicles built 03/2002 onward. The modules are not interchangeable.
The driver and passenger heated seats share a common battery and ignition feed. A shared ground source supplies the heated seat control switches. When the heated seat control switch is pressed with the ignition switch in RUN or START, a momentary ground signal is sent to the heated seat module. The heated seat module then supplies power to the heating element circuit. The cushion element and seat backrest element are wired in series and powered by the same output. The heated seat module also will ground the separate indicator circuit at the dual automatic temperature control (DATC) module display panel to indicate an ON state. The heated seat module will remain on until the heated seat control switch is pressed and a momentary voltage signal is received, or until 10 minutes expire. If the ignition source is removed from the module, the heated seat module will enter an OFF state and will not return to ON until the switch is once again pressed with the ignition switch in RUN. The heated seat module is designed to heat the seat to 37.5?C (99.5?F) and maintain the temperature until time-out or switched off. This temperature is maintained by the heated seat module monitoring the temperature sensor located in the seat cushion element, and adjusting the current flow to the heating elements.

Heated seats in 2007 Lincoln MKX not working. I puch the button to turn them on and they light up for a second then go off. What would be the cause and solution. If it was a major problem would effect...


Help anybody?
I have a 2010 Lincoln MKX with heated and cooled front seats. However, when I try to turn them on (85% of the time) they don't work. Primarily when it's cold the heated seats won't stay on... The light turns on for a fast count of 1-5 and then turns off. This has happened since the car was new and I've had it into the dealer 4 times to have it fixed (with no resolve). In their defense they suggest it's fixed each time because they test the heated seats when the vehicle is warm in the shop. Unfortunately, this is nearly the only time it stays on.
I would love to recommend a suggested fix to the dealer as they don't seem to be able to repair it... Any ideas???

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.

Drivers heated seat won' work


Probably a fuse!
Under the dash on the drivers side or under the hood.
New cars have them labeled right at the fuses not in the manual!
Hope this is helpful.

Good Luck!
