Hey guys, I've tried to search but I can't find the diagrams that I need. I'm having a problem with my 4 wheel drive. NOTHING is working. No lights, the switch seems to do nothing and obviously no four wheel drive in any position. I've been on the drivetrain section and learned a lot but need some wiring diagrams.
I've checked the simple stuff like fuses under the hood and on the side of the dash and they are all good. I did find a relay box under the dash by the throttle pedal but no markings so I don't know what relays do what. So if I could please get a diagram of that and what the relays are for.
Also, I need diagrams of the 4 wheel drive switch, where it goes, the GEM module, TOD relay and everything related to four wheel drive. I'm thinking the module is bad but want to be able to check everything else before I go get a new one.
I did ohm out the 4 wheel drive switch and found 388 ohms in 4L.... 1111ohms in 4H...... and 3920ohms in Auto. I'd like to find the specs on the switch to see if that is good or not.
Also any help or experiences would be greatly appreciated. Thanks in advance!
