Just finished repairing the orange power seat wire behind the drivers seat this weekend. Today I needed 4x4. the light was on for 2wd. I pushed the 4hi button all the lights went out and no relay noises or anything. I checked fuse it was ok. What did I screw up? Where is the 4x4 relay?

 

bump!!! I lost all the 4wd lights. They where flashing on and off...now they are all off and 4wd wont work...

 

3-button switch or 4-button switch?

 

2002 Jimmy SLS 3 button....ok after running up and down my stairs and reading 50+ topics... All wiring looks good now, and I CAN NOT read the TCCM with a jumper. One of the wires to the TCCM was badle corroded. I think it fried the TCCM. Im gonna try get another one tomorrow, cause I fixed it, and still nothin.

Does anyone have a pin out of the wires going to the TCCM, and what ones to the TCCM should have power, and what ones leaving the TCCM should have power? Im gonna buy a Haynes manual tomorrow.

 

Should be some wiring diagrams around here somewhere. It probably will not tell you want voltages are supposed to be on what wires, but it would provide the main power and ground wires.

 

Ive been looking for some diagrams, but either I cant search right, or im no where near the right wording to find them...lol

 

I found them. I made it easier for everyone by putting them in the NV233 transfer case thread in the Tech Article (DIY) section that error_401 created.

Thanks a lot man!!!!

 

No problem.
