wiring diagram

Does anyone have a wiring diagram that shows 4 wheel drive components on a 93 explorer?Thanks.

Its my brothers exploder.The 4 wheel drive button isnt lighting up.There are 3 relays rear driver side.I dont know where the relay is at for the actuator motor?I wanted to check it out before he spends money on new actuator. Anyone have a link or maybe a friend with a link to a diagram.Thanks.

Everyones shift motor goes bad and there is next to zero chance of an electrical problem. These are easy to take apart and clean. This site has details.

i had the same problem with my '92 EB. I'd hit the switch on the dash and got no light (the switch or the instrument panel) but i heard a click from the relay in the cargo area. I took the motor off of the transfer case and took it apart. I cleaned it with some electronic contact cleaner and put it back together and it has worked perfect ever since

btw, the three relays in the back are for your taillights and trailer connector...not the 4wd...the box located about 1 ft. further forward is for the 4wd...Good luck
