Ok so i have this 1997 ford expedition that has what i'm guessing an electrical problem, When I park it for a little while... (say after work and I get home and it sits in my driveway over night) and the next morning I will have to adjust my mirrors because they moved out, also the seat has to be adjusted, I don't have to slide the seat back or forth, its just one setting... the pitch of the seat is to far up so I have to put it back down. This car is not equipped with a memory system of any kind. I don't know what it could be, I have looked everywhere, my brother said it could be a relay, but I don't know. Any guesses? Any help would be greatly appreciated thank you.
