As for The solution on your problem — sorry, I don’t possess the foggiest as my Blazer doesn’t possess the “Vehicle” feature. Ya gotta individual one of them extravagant vans! You know what I’d say even though? If it ain’t broke, don’t touch it! Thanks on your responses!
Initially, I apologize for the hold off in responding — I had a nuts handful of months all-around the vacations and didn’t do Substantially blogging.
I checked the wiring harness behing the passenger kick plate and it is okay and in tact. The wires are all producing Get hold of.
The simplest way to check the suspension once the auto is lifted is always to grip each wheel and shake it, both equally horizontally and vertically. If you do not come to feel A lot movement, your suspension is most likely in fantastic condition.
Here are some far more photographs of your TCCM. They're not mine, but I Actually can’t recall who sent them to me presently (I just identified them although cleaning up the backend of the positioning and didn’t know they had been there.). If they are yours, let me know And that i’ll submit Picture credits. Thanks!
It’s hard to say what your dilemma is. I’d get started with checking out the encoder motor — If you're able to listen to it run briefly, then what I might do is get it from the transfer case and check out to interact 4WD then — check out the motor and find out what it does — consider it in all modes (2Hi, 4Hi, 4Lo) and enjoy the motor. If that seems to be OK, the following detail I'd personally do will be to try to manually shift the TC While using the “tab” that should now be sticking out of your side of your TC (beneath the encoder motor that you choose to eliminated) — it is this tab which the encoder motor turns to have interaction different modes.
i place it in park, and once more absolutely nothing. the only way to interact it (no buttons flashing at all when in park or generate) is To place it in neutral, and yet again only will go into 4low.
PS – nope, no other title for that Encoder Motor, that I know of. It’s Situated around the facet from the transfer situation and it what does the physical shifting among “modes” (2Hi, 4Hi/4Lo).
Repeat at the method behind Every tire. As long as you use string or wire that does not extend, you can obtain an exceptionally precise measurement in this way.
I was really pleased every time they held, that’s obviously! I mounted the module again within the body, reinstalled the kick panel and my four×four was back in organization.
You are aware of, apart from what I’ve posted above with regard to the forks/gears, I don’t really know Substantially about them — I had the issue described to me though I had been driving household about the freeway in hurry hour site visitors. I in no way really asked any questions even further than that — ’cause my 4WD labored!
I’m not totally certain what triggers the lights to simply blink then not go into gear. The very first time I put the Blazer in 4Hi this Wintertime, it did just that…. I had to put it in neutral for it to enter 4Hi. Due to the fact then, it can shift on-the-fly. Why? I don’t know. There has to be sensors either within the TC or the encoder motor to Enable it know when it's got arrived at it’s meant method… I’d suspect it’s part of the encoder motor, but I’m just guessing.
Doesn’t audio very good. It seems like what I just went through — and it turned out to become the gears/forks within the transfer scenario. I initially seen that I experienced issues popping out of 4WD, then I started out noticing 4Hi “slipping” out and in.
Heck, if ya need to “hack” it together, you could possibly normally eliminate Visit THIS Site the module from your aspect from the transfer situation, Slice a gap through the floor and put an actual shifter throughout the floor and attach it into the pin over the transfer scenario (I wouldn’t propose this on an ’03… probably depart that trick for one which is falling apart and you simply don’t want to spend An additional dime on it!) — Then you can certainly shift into 4WD manually (All over again… NOT RECOMMENDED over a Road car or truck!!).
