Power Seat Problems

[mekstrum]

I am Expieranceing Power Seat Problems. Front Driver seat Has no power at all. Was fixed last year when I had a whole lot of problems with this vehicle. Both seats did not function, 4 wheel drive problems rear liftgate problems. The dealer said all the problems were with electrical control modules and numerous of these were replaced at considerable expense. Anyone else out there with these problems? Of all the threads listed i can see that I am not alone however I have not found any power seat postings!

The power seats have their own computers in them (look under the seat after you take them out). There are four wires going to it: Big Orange (main power from a 30A circuit breaker in rear fuse block), little orange (from 5A circuit in same box), ground, and a Serialbus2 wire which controls the whole damn thing. The switches in the door (for heat if you have it) run commands over the bus to turn the heaters on/off. If you have memory seats...they are controlled the same way.
It sounde like you have some problem with the rear fuse box...or the BCM, which acts as the bus controller.
