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.

My 2005 Yukon xl driver seat heater won't work. Where is the fuse for it?


Not a fuse problem , more likely a burnt out element .
CHEVY GMC SEAT HEATER TROUBLESHOOTING YouTube

Your best bet , take it to a qualified repair shop.

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

Do you know what a electronic module is ?
DTC B2425 or B2430
Circuit Description
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 Descriptors
This diagnostic procedure supports the following DTCs:
• DTC B2425 Driver Seat Heater Circuit
• DTC B2430 Passenger Seat Heater Circuit

Do you know what a DTC - diagnostic trouble code is.

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

Airbag light on


Is there a passnger airbag light also, on this car? If it's the passenger airbag light, it could be a problem with the switch and/or sensor for the passenger seat. Either way, you really should get this to a dealer ASAP since when the light is on, the airbag is inoperable.

Driver seats mountaineer stop working, passenger power seats work


The next time the seat is inoperable pull the switch out and test it for a voltage signal that should be present when the button in question is operated. The switch is the most common issue that I have seen, but hold on replacing it until the switch is tested.

What's involved and cost to install power passenger power seat in 2004 Ford Freestar Limited?


That is a real hard question to answer. Are you talking about REPLACING a power passenger seat? or are you talking about installing a power passenger seat in a vehicle that was not originally equipped with a power passenger seat?

The latter would be a MAJOR undertaking. The seats are controlled by the computer, so any addition of seats would require reprogramming of the computer to handle the extra seat. Also, I am not sure if the wiring harnesses would be there. t is possible that the wiring harnesses are already present, but I would have to see the vehicle to verify that.

Then there's the cost of the seat itself. Where do you intend to get one? The cheapest way would be to find a vehicle in a salvage yard with power passenger seat that has the same interior trim codes as your vehicle. (So the upholstery will match) The other option is to order a NEW seat from Ford...VERY EXPENSIVE! Probably around $700. This is just for the seat and does not include the price of installation labor and reprogramming.

Now, if you are talking about replacing an existing power seat, I have to ask this: Why are you replacing it? Is there something wrong with it that makes it not worth repairing?

Sounds like you have a short somewhere in the seat wiring. Check wiring under the seat for shorts.
