electrical problems or something???

Ok, so here is the info on the car. It is a 1991 GTP with the 3.4 DOHC with the 5spd tranny. I just bought the car and i am having a few issues. The power door locks, power mirrors, and lumbar controls don't work, but the windows, and all other electronics do. What would cause that. I just got the car and the PO said he thought it might be a relay or something. I check all the fuses and they are good. anyone have this problem before and know how to fix it? Thanks for any help.

hmmmm You say all the fuses are good.

 

I've had this happen before when spare change fell into the cigarette lighter outlet and blew the courtesy fuse.

 

Worth double checking.

i will check them again. i thought it might be one of the relays in the fuses box in the engine compartment but i wanted to see if anyone else had this problem before i start doing things i dont need to.

If its one of the relays, get a 12v source, and get some small aligator clips and test it. If its good youll hear it click as you apply the 12v source
