Hi i have a 97 f150 with the 4.6ltr in it. My 4x4 is not working either. It is stuck in 4 low but i did work in 4 high until i turned the switch. Now it wont come out of 4 low but all 4 wheels are engaged. The light on the dash does not come on either. I took the "gem" module out from underneithe the dash and cleaned it also all the connectors that i could find. I also put a new switch in the dash. Sounds like a relay could be bad but i dont know where they are at or how many of them there are. If anyone could give me a clue on where or what else 2 check i would greatly appreciate it thanks
