Just one Take note… not all vacuum switches can be found around the firewall. If it’s not there, Verify the highest of your transfer case!
Do the identical on the other side. If there's no location over the tire where by the tread is flat, you might require to suspend your marking Instrument having a clamp or related stabilizer.
I checked the wiring harness behing the passenger kick plate and it is fine As well as in tact. The wires are all making Get in touch with.
The support 4×4 mild typically indicates an issue inside the transfer scenario. Complications participating a disengaging would seem to substantiate this.

Thought I might give you an update on my 4wd problem. As I indicated in my initial post, I'd a vaccum line unfastened. I assumed it went into a canister within the fender, what’s a lot more, I believed it experienced a thing to accomplish with my 4wd not working. Very well, which was the situation. I discovered the attachment for that line on the canister. I acquired a different vaccum line (the just one I had was weathered), installed it and hooked it up towards the canister. Then I went to your muddy spot in a very sub-division next to mine, drove in to the mud in 2wd. I just sat the spinning the rear wheels.

Hmmm… doesn’t seem similar to a TCCM problem… Seems a lot more like an encoder motor challenge, or maybe a transfer case dilemma.
Sorry with the extensive submit, I just don’t know the place to start. Like I explained I do think my 4×four operates it just won’t “hold” it in 2HI? Thanks for any help.
PS – the “encoder motor” would be the part that “holds” your TC in the varied modes (perfectly, that’s not one hundred% exact either — the encoder motor shifts from just one mode to one other — sections In the TC essentially “hold” you in that manner — in my situation, it had been a list of “forks” with plastic bushings that wore out — which isn't going to audio like your issue).
If by unplugging the TCCM you hope to the car will default to 2WD — it won’t. So long as it’s basically Performing and driving your axle(s), go away or not it's and acquire it into a mechanic ASAP.
