07 09 GM Suv 2008 Escalade Heated Cooled Seats Repair Suburban Yukon

Don't think fuse problem , use's a circuit breaker . They don't fail . The elements are probably open . 2007 Cadillac DTS Heated Seat Repair

are the wires under the seat conected properly check fuses or relays if these are ok its probably the heat mat under the seat its self dont think there that expensive to replace cheers ivan

Your solution is a front passenger door module (FPDM),before you replace it check for open fuse in the engine junction fuse box,I dont know the fuse number but it is a 25 amp fuse.

Could be the swap valve/damper not opening to allow air to flow thru heater core in rear or control switch not telling it to change.

YOU HAVE SHORT IN THE POWER SEAT SWITCH.YOU DONT WONT TO DISCONNECT WIRES TO SEAT POWER SEAT MOTOR BECAUSE YOUR SIDE IMPACT AIRBAGS ARE CONNECTED TO POWER SEAT CIRCUIT.DONT MESS WITH POWER SEAT YOU CAN SET OFF AIRBAGS,LET DEALERSHIP CHECK IT OUT TO BE ON THE SAFE SIDE.

It sounds like you have an over-current problem with your seat controls that may be causing the self-resetting circuit breaker to trip. It may also just be a weak circuit breaker. These tend to get weak and trip easilly if they are tripped several times. It is possible that your problem before replacing the seat module caused this. It is also possible that the seat motors or heating elements have a present problem that are causing this. If so, this might be the cause of your module going bad in the first place. The right way to diagnose this would be to scan your Body Control Module for fault codes and to see if there is any information/data that can lead to to an effective repair.

You could also try replacing the circuit breaker first to see if this fixes the problem. It is the "Seats" Circuit Breaker in the Instrument Panel Fuse Block. it is a 30-Amp, self-resetting breaker.

The only problem with doing it this way, is that if this problem is in fact what caused your seat module failure, simply replacing the circuit breaker may cause a second module failure.

You will need to replace the switch module, it is the only thing that can cause this to happen

The controller could be bad but I would probe the related wiring first. From your symptoms it sounds like something can not handle the electrical load. You turn the F/R seat heater on but then you turn on the F/L and the whole system fails. It does sound like the source of the problem will be under the drivers seat. Testing needs to be performed to confirm and identify the source. Both seats share the same fuse and ground. This circuit may have a damaged wire or connector somewhere. Inspect and test as much as you can. Also look underneath the seats for anything. Customers are not aware that personal belongings and trash get pushed underneath the seats and will damage wiring. Also excessively moving the seat forward and back will weaken the harness over time. Please write back and let me know what you need. If it is more diagnostic information or suggestions just let me know. Good Luck

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
