    2000 K2500 4WD Issue, Wiring Help

    UPDATE: I was finally able to get the truck in the garage and work on it. Short story is the 4WD is working again! Details below. I swapped out the transfer case switch for a new one since they are only $12 each. Then I cleaned up ground G105 which is on the front of the engine block. G105 and...

    2000 K2500 4WD Issue, Wiring Help

    @xXxPARAGONxXx I think your attachment is just what I was looking for! Much appreciated. Does your manual list where grounds G105 and G202 are located? The '98 manual I have says they are located in the following spots, wondering if they are the same for 2000: G105: RF of Engine block G202: RH...

    2000 K2500 4WD Issue, Wiring Help

    Well it snowed and the truck is at the bottom of a hill so I won't be working on it for a bit which might be good. My fall back plan if I couldn't get it sorted out was to go with the a Posi-Lok 4x4 but it seems they were made specifically to replace the thermal actuators (up to 98) so that...

    2000 K2500 4WD Issue, Wiring Help

    No worries @1998_K1500_Sub, don't want to waste your time, the more I research the more I'm thinking that the 99+ GMT400s are just a bit different than the 98's and below when it comes to some of the wiring. I'm starting to think I might have to track down someone with specific knowledge on the...

    2000 K2500 4WD Issue, Wiring Help

    @1998_K1500_Sub Do you know which pages of the GMT400 transfer case info.pdf you attached are applicable to a manual transmission truck with the 4WD shifter on the floor? The page titles don't seem help much but I'm guessing they have to be for different versions. Here are my best guesses...

    2000 K2500 4WD Issue, Wiring Help

    I have a 2000 K2500, manual transmission with the 4x4 shifter on the floor. It has stopped shifting into 4WD and I've spent the past few days reading posts and trying to track down the issue but no luck so far. Looking for leads on what to do next. Main issue is that power isn't getting to the...

    Electric issues with 4x4, fan & dash lights

    Update: The 4x4, dash warning lights & fan are all working again! I rigged up my voltage meter on a long wire running from the positive battery terminal and went around testing the voltage drop. Battery was 12v, engine block was 12v, frame was 12v, firewall was 12v and the ground near the OBD...

    Electric issues with 4x4, fan & dash lights

    Thanks all! I'll have a closer look later this week looking for voltage drops at the grounds once it gets above 14 degrees and stops snowing out there :waytogo:

    Electric issues with 4x4, fan & dash lights

    Thanks for the suggestion Brandon. I found the ground above the OBD2 port and it looked like it was in good shape. I still disconnected it, cleaned it up and then reconnected it. Unfortunately still seeing the same issues with the dash warning lights, 4x4 and fan. Let me know if you have any...

    Electric issues with 4x4, fan & dash lights

    Hey All, Looking for a bit of help on some electrical issues I'm having with my 2000 K2500 (has the 454 in it). Some of the dash warning lights started flickering on and off a while back (ABS/seatbelt/e-brake) but not a big deal. Truck still started and ran fine, then the ac blower fan would...
