Most of the time the element in the seat is bad causing the no operation, usually the light will come on and go out or just with no operation.

Seat heater comes on by itself in 2004 yukon denali


Heated Seat Components
The heated seat system consists of the following components:
• Driver and passenger heated seat switches
• Driver and passenger seat back heater elements
• Driver and passenger seat cushion heater elements
• Driver and passenger seat back temperature sensors
• Driver seat module
• Driver door module
• Passenger door module
When there are modules involved in the operation of any componet that's acting up , the module's electronic's could be the culprit ! But without testing who's to say what the problem could be !
I would have it check for DTC'S
DTC B2425 or B2430
The driver and passenger seat heaters are controlled by the driver seat module. Power is supplied to the driver seat cushion and back heater elements through individual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the driver seat module through individual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the driver seat module in order to control the seat temperatures by regulating the current flow through the heater elements.
DTC B2435 or B2440
The driver seat module relies on inputs from thermistors installed in the driver and passenger seat backs to control heated seat temperatures. The thermistors are 2-wire sensors supplied with a 5-volt referenced signal circuit and low reference circuit from the driver seat module. Resistance through the thermistors varies with temperature causing the heated seat sensor signal circuit voltage levels to decrease as the seat back temperatures rise.
Install a scan tool.
Start the engine.
Turn the heated seat ON.
With a scan tool, observe the Heated Seat Sensor parameter in the data list for the driver seat module.
Does the scan tool indicate that the heated seat sensor parameter is within the specified range?
0.078-4.94 V

Trying to find which fuse is for the heated seats on a 2004 ford explorer sports trak


Heated Seats
This system allows the electrical heating of the front seats on passenger demand.
The components of the system are:
  • the seat heating elements located in the seat cushion and backrest.
  • the heated seat control switch, located on the seat side trim panel.
  • temperature sensors located in the seat cushion heating elements.
  • heated seat relay.
Do both front seat heaters not work ? Do you know how to test electrical circuits with voltmeter ?

My 2003 gmc Sierra driver side door panel quit working, locks quit, seat heater quit, windows quit, passenger side works fine


The most likely culprit is your driver's door control module... it's built into the driver's window switches. Double-check all your fuses before replacing any parts.

I have a 2002 Oldsmobile Bravada...Yesterday all of a sudden my passenger's side window stop working(up and down)...the power lock and the heated seat all stop working on my passenger's side...?


If you have an Owners manual, try looking for a fuse panel diagram. Your could have a bad connection inside the doorpanel which shorted the fuse. The seat drive motor must be wired to a separate circuit coming from the floorboard and its okay.
The circuits are wired independently to protect the lighter wires from the heavy drain of the seat motor. If you had the heated seat function working on the seat at the same time as adjusting the seat motor it would be too much for a single circuit, so they gave you two circuits.

If you are going to work on the door panel, disconnct the NEG battery cable so you won't short out something taking it apart.

Another Repair place you might try is a Glass Replacement shop. They install the inner workings of window tracks daily and remove the door panels to do it. They would be able to find your wires, test your window motor, and get you on your way quickly.

Unlike a Dealership, they have a high turnover of glass installations daily. Some even come to your house to repair your problem. Your car would be repaired more quickly with these services.

Heater doesn't blow out warm, cold only. Fan and air conditiong work fine. Appears heater core is ok. Is there some kind of switch that possible broke inside the dash/


yes, the blend door actuator may have failed. So are the heater hoses hot going into the firewall? I assume that is why you say the core is OK.

To check the blend door,
  1. Remove the lower trim panel from the passenger side of the instrument panel.
  2. Disengage the trim panel from the passenger side of the center console.
You should be able to see the actuator there. Try changing the temperature setting to see if the gear turns in the actuator. If not, remove the actuator and see if you can rotate the blend door shaft by hand. If the door is jammed, you may have to take the heater box out to free it up. If the door works OK by hand, either the actuator is bad or the switch is bad. If you could hear the actuator clicking when you were checking it, it is getting power but is stripped. If it was not clicking, I recommend you verify there is power to the actuator by probing the connector with a test light while changing the temperature setting. If there is no voltage, the switch may have failed. If you have questions, please let me know.

NO COST and fast PROCEDURE TO FIX IT:

1. Sit in vehicle, on seat next to problematic window
2. Ignition key is on
3. Door in question is opened (in case you closed it)
4. While door is open, press and hold power window button in desired window travel, keep button pressed !!
5. SLAM hard the door closed with one hand while other hand holds button as per #4.
