As for The solution on your question — sorry, I don’t provide the foggiest as my Blazer doesn’t provide the “Auto” function. Ya gotta possess one of these fancy vehicles! You determine what I’d say although? If it ain’t broke, don’t touch it! Thanks in your comments!
I study all the reviews about American vehicles and similar to a idiot I purchased this Blazer mainly because it gave the look of an excellent offer. I’m however trying to figure out several of the electrical challenges out. Our great car or truck companies assumed they were planning to sell junk eternally and we ended up likely to preserve purchasing it. Mistaken!!!! That is my final American vehicle until eventually one thing modifications. Just this 7 days I junked my Pontiac Together with the well-known Quad4 engine that broke a connecting rod 2 times.. A pair decades in the past I scrapped my Dodge Caravan once the trans mission EXPLODED two times. And that i do mean explode! NO MORE GM, Ford, Chrysler!!!
Very first, you should Observe that I am NOT a licensed mechanic! I like car work and do a lot of my very own operate, and so obtain the knowledge which i share inside of my web site. OK, so more than enough on the disclaimers currently!
No difficulty at all… that was my sole intention… that will help Other folks with a similar challenge (and help you save a ton of cash also!).
Sadly, I don’t know the answers to most of your concerns — I am able to guess, but that’s what it’s gonna be, a guess.
Sad to say, I have not encountered what you're describing and will only offer recommend for things that I, Individually, have performed as I am not a mechanic. I don't know what this pin is, or how significantly it should shift.
If I needed to guess — possibly your encoder motor is shot, or poor wires over the TCCM. When you’re genuinely into it, I’ll submit the schematics for the wiring with the program — this will allow you to trace and examination points together the technique to pinpoint the issue. (I really have to scan them, so it will not be these days!)
I'd personally Test your Substantial orange wires as you're finding +5VDC logic as the lights are approaching around the sprint. The +12VDC is employed for the encoder motor — Check out to you should definitely have +12VDC at the two the large orange wires (These are proper beside each other… and There's two large black wires beside them that are floor). Notes: All black wires are ground — all orange wires are energy (warm). You will find there's 10A fuse (#fifteen) for your 4WD Visit This Site method, situated in the fuse panel. There's a 20A fuse, located under the hood, that is certainly also for your 4WD program (I’ll have to look up the fuse variety). The 4WD process also pulls through the 10A courtesy lamp fuse (#10).
Like I reported, I'll make an effort to make sure to get some a lot more pics — ideally this can assist you obtain your module nevertheless! Regards;
Make your changes. Depending on the kind of steering you've, there are two different ways you may regulate your toe. In case you have rack and pinion steering, it is best to turn the internal tie rod itself. Spinning the rod will change the toe in or out. Should you have a parallelogram linkage procedure, there will be altering sleeves that you could transform to regulate your toe.
PS – the “encoder motor” is the section that “holds” your TC in the different modes (very well, that’s not 100% correct possibly — the encoder motor shifts from a person mode to the opposite — pieces In the TC truly “hold” you in that manner — in my scenario, it was a set of “forks” with plastic bushings that wore out — which does not sound like your problem).

It only took a few minutes to Track down the module and the situation was clearly noticeable right after removing the module with the body to possess a closer seem. The wires/plug connector were being terribly corroded on a handful of pins — which led to two damaged wires (pin #one, gray w/ black and pin #six, orange).
Chris says: February nine, 2008 at 4:00 pm Initially I have to say this website rocks!! I do think you might be doing an magnificent provider. I've read a lot of of such issues but have not observed one which matches mine exactly. A while back had the classic encoder motor challenge in which the truck would go into four-lo or two-Hello, but would flash and default to 2-hi when 4-Hello switch depressed. Very well Examine vacuum actuator underneath battery, Tccm, encoder motor plug,etc and all was fantastic. For the reason that my battery was disconnected the DTCs ended up reset and lo and behold my 4WD was Operating again. When 4wd was disengaged I might receive a whirring sound out from the entrance close, like 4wd wasn’t totally disengaging the entrance diff. I would halt the vehicle for a couple of minutes and it appeared to go away. One other day, on the way in which to work the sounds wouldn’t go away, so i tried putting it out and in of four-Hello a number of instances, till it blew the fuse.
