4WD Electrical Issues
Hey everyone in a bit of a jam,
My 4WD auto with 4.6 just stopped working (noticed first time since summer). I have a 97F150 with a electric transfer switch on dash. I have nothing happening when i select out of 2WD....no lights on dash, no clicking relays...nada. Instead of testing everything (due to time restraints) and of course checking the obvious fuses i just took some mechanical friends advice and replaced transfer case motor. Nada. Replaced switch on dash. Still nada. Tonight im going to swap out the Transfer Case Shift Motor Relay in dash behind radio and the Transfer Case Electric Clutch Relay / RPO relay block up behind the glove department in dash.
I really dont think its the GEM b/c everything else electrical wise is workin fine....is it posssible the GEM could still be the issue?
Is there anything else anyone can think of that im missing?

Why not take some time to see what is or is not happening instead of just replaceing parts?
When the switch goes to 4H you should hear the transfer case motor run to the first position and the front axle actuator clunk in with the motor running.
Yes the GEM could be suspect.
The dash switch signals the GEM as the first action taken in the process.
When the process is complete, the GEM turns on the dash lamp.
It's more complex than you know at this point.
Good luck.

Thanks Bluegrass 7 i usually dont jump into things like this but i paniced a little....holliday season-no time to do anything. Infact i didnt get to replacing anything last night....doing it tonight.
Anyway im 90% sure when i turn the switch nothing is happening to the transfer case motor. I havent actually put my ear to it while having someone turn the switch but i hear or feel nothing when i switch to 4H.
When i test it tonight while i have someone that will be the first thing i check. If it is not doing anything then i can suspect the GEM first and inspect that.....who knows maybe i do have a windshield leak ive read about in other forums.....next i guess i would follow the wiring diagram to whatevers next either the TCSMR or the TCECR.
Thats good to know the GEM is the first and last stop on completing the circuit to illuminate the dash lights. This is a complicated issue...def wish i had a manual transfer on the floor.
I have a guy stripping all the components associated with this process out of a junkyard truck and will begin the process tonight.
Any other suggestions or lil tid bits that would help?? Besides slowing down and thinking through this logically and not just replacing parts. lol
