The fuse blew a couple weeks ago and everytime ive tried to replace it it blows again just seconds after starting the truck. I removed the kick panel and found that there was corrosion on the female end of the harness, tugged on the most corroded wire (number one, grey+blck) and it broke right off by the looks of it. Im wondering what the next step is? Im tempted to get a used harness and just cut the wires and hardwire it but as you can probably tell i dont know much if anything about this. Any help would be great, thanks.

 

That fuse powers the TCCM, dash switch, front drive engagement switch, PCM, and the front axle engagement solenoid - wiring schematics - NV236 Wiring Information. Any one of those items could be causing it to blow, but the TCCM is the most common. Check for corrosion on the connector terminals at the TCCM (located behind the passenger side kick panel).

 

Okay so there is corrosion on the tccm connector, i finally found the time this wkend to work on it and i cleaned it all up, one wire was extremely corroded and broke when i touchedit so im going to put another pin on it and see if it works but i was wondering if the tccm is fried now or if this will work for now...also wondering what a used tccm costs roughly

thanks
