my power window and locks do not work. I don't know if it's as simple as taking the truck to the mechanic and they can fix something in the wiring.. or if it's more complicated than that. I think there's a short in the wiring or something.. because as I drive they will push themselves and I can hear the locks going up and down and such.

your door locks have a cirucit breaker int eh fuse block and if the door locks work occasionally then it may be a short and knocking the breakeron and off. Usually on trucks this old the harness is broken between the door and post. also check your fuses. in the convience center under teh left of dahs by the steering coloumn there is a a diode it looks like. those cold be bad as well. there may be a relay as well though too.
