The next Inspection is from the motor bay superior up on the center from the firewall. Inspect for vacuum at the switch then ensure the hose is’nt damaged resulting in leaking (Mine was damaged off) Excessive warmth in the engine compartment will problems vacuum hoses and extreme curves or bending will cause issues with hose decay and failure.
As I stated, I have not examined any in the button wires, as I have not had that particular dilemma (yet) — so, before you decide to make this happen, you will want to validate what I'm saying is genuine.
Now, I don’t know if I rush appropriate out on the seller as there generally is a couple of compact difficulties that will induce this affliction, dependant upon what that particular design/12 months has been programmed to detect.
Your comment about stepping into slippery problems along with the 2Hi light goes out… The one thing I can visualize will be the TCCM (Transfer Circumstance Handle Module) can have corroded wires, which was the first topic of the thread. Does this happen instantly when you get into slippery disorders?
Here are a few a lot more illustrations or photos in the TCCM. They're not mine, but I Truthfully can’t try to remember who despatched them to me at the moment (I just located them whilst cleaning up the backend of the location and didn’t know they were being there.). If they're yours, let me know and I’ll put up Picture credits. Many thanks!
Should you don’t thoughts, I'd a great deal want to publish your reviews — if you want, I am able to go away your title out — naturally, the selection is yours and I'll regard any final decision you make, just let me know.
Ideally, In addition it presents Other folks the encouragement / assurance to tackle Work opportunities similar to this on their own!

You furthermore may want to examine the wires with the encoder motor as they are exposed to the elements and *could* be wheel alignment near me harmed by one thing flying up beneath your motor vehicle (not likely, but doable).

Unfortunately, I'm able to’t offer you a definitive reply to the problem, but if I'd to say, I’d glimpse in other places, besides your TCCM (encoder or transfer circumstance)… but nonetheless, I’m not a mechanic possibly… so I am just guessing!

Basically, test Every single of your strains — if they are all warm when in 2Hi, then when you test to alter to 2Lo, among the traces should go minimal (0VDC) — a similar really should come about with 4Hi. So, if you are attempting to engage 4Hi and you also’re guaranteed There's energy at pin 5 (4Hi button sign), and Not one of the strains alter when endeavoring to improve to 4Hi, I'd suspect the TCCM. If your encoder signal line DOES alter, then the transfer case encoder motor module is bad.
Sorry, can’t make it easier to with that just one — the Silverado I don’t know. It seems like you may have AutoTrack nevertheless. As I stated to your past poster, I don’t know Substantially in any way about AutoTrack, apart from it’s a “set and forget about” kind method.
