couple weeks ago everyting was good, this week both heater on both seat dosen't work. even the light on the heater switch won't light on, there is also no life at both switch and all connecter sims to be properly connected, im afraid it might be the computer ...
well there is no fuses specialy for the heater but all the fuses and relay have been checked...there is some fuse and relay for the power seat but all the seat controls work except the memory for the seat position...
Having a little problem diagnosing your problem, I don't have a drawing for the seat heaters.
Our buddy "the roadie" may pop on here later, I am sure he has the necessary drawings.
Usually there is only one problem when something like this fails, so I'd be surprised if both front door control modules have failed. Particularly, if all other door functions work.
The heaters will draw a substantial amount of current; and most heater buttons are non-locking, push to operate switches (this lets the heater turn off when the key is turned off). This switch type and the heavy current draw means a relay (or two) will be inserted into the circuit.
Because of the heavy current draw, heaters only work while the engine is running, so it is logical to look in the under hood fuse box for the fuses.
