Your problem sounds much like ten Some others above you — in the event you haven’t observed The solution in what I've posted To date I, regretably, won't be equipped to assist you and propose taking your motor vehicle to a mechanic.
Hmmm… how ’bout warm glue? I basically plugged in the most crucial connector to your module (immediately after sealing everything up with dielectric gel… which might have prevented this to begin with) and afterwards inserted the wire into pin #one and produced the link, and the same for pin #6.
One other location for 4WD vacuum is beneath the battery — but that is very a length through the motorists doorway, although everything can be done.
Usually, that is certainly telling you that there's a difficulty from the transfer circumstance — hassle codes really should be set, so have your car scanned by your mechanic. I haven't any expertise Along with the 4WD services light, so besides that, I have no even further data.
Are there lights over the press buttons? In either case, the button module simply snaps into place while in the sprint and is not difficult to receive out. Pull the button module and look for loose wires to the back on the change.
Naturally, I can’t warranty This can be your dilemma, Primarily online, And that i hope it isn’t — but I might have it checked out professionally.
Mainly, this could emulate the button currently being pressed and should result in the TCCM to interact 4Hi. If it does not, the issue is for the TCCM, most-most likely. Once again, Verify pin 5 within the TCCM. You might also wish to test applying electric power to pin 5 immediately for the TCCM and find out if it engages 4Hi.
Set a check lead (volt meter) around the output on the 4Lo button… when you press 4 Lo, does the meter suggest that there's ability leaving the button? (It should, if what I am examining Here's correct… And that i’m reading through it correctly.) Now, do exactly the same for 4Hi (do both of those checks in park) — does it output similar to 4Lo? If not, you may wish to examine the harness on the buttons a bit more cautiously 1st, then try out making use of energy to your output side of the 4Hi button (the exact same level since the output from 4Lo, no matter if it be +12VDC or +5VDC… I’m pondering it ought to be +12VDC nevertheless).
The subsequent Visit THIS Site point I seen was which you mentioned the lights on the dash will flash after you push 4Hi — this lets you know that the button for 4Hi is Doing work, along with the TCCM is accepting the signal from it.

I am able to’t thank you enough for this website. I obtained a 95 Jimmy on an impound auction for $320. I received it started off, and sure adequate no four wheel travel. I recognized the sprint buttons appeared like they didn’t simply click, they lit up when ingnition was turned on, then 2 hi stayed lit, thats all I could get them to perform. So I grabed on to the two wheel button and gave just a little tug and it poped appropriate out in the sprint.
