Fantastic! Many thanks yet again for that suggestions, and allowing for me to article your feedback — They're appreciated!
I read the many evaluations about American autos and similar to a idiot I bought this Blazer since it appeared like a superb offer. I’m however trying to figure out a number of the electrical difficulties out. Our terrific vehicle companies assumed they have been planning to offer junk for good and we ended up about to hold getting it. Mistaken!!!! This is certainly my past American automobile until finally some thing improvements. Just this 7 days I junked my Pontiac With all the well known Quad4 motor that broke a connecting rod two times.. A couple years back I scrapped my Dodge Caravan after the trans mission EXPLODED two times. And that i do indicate explode! NO A lot more GM, Ford, Chrysler!!!
I, myself, don’t know of any vacuum Positioned with the transfer case, but I will attempt to learn for yourself (I've a transmission shop from the family members — I just referred to as, although the knowledgable one is not really but in). The TC is incredibly near the entrance of your vehicle — do you think you're absolutely sure the vacuum is not coming with the firewall region?
Man, if it’s simply a button assembly, don’t stress — there are no electronics in the button assembly — They're just that — buttons (switches). Meaning, it shouldn’t cost all that A great deal. The most expensive component would be the dealers labour amount.
I’m undecided why you'd choose to pull the cable to the entrance diff — I thought you said the front axle turns when in 4WD although not 2WD? If that is the scenario, the axle is engaged (that means the cable is remaining pulled).
Of course, I'm able to’t ensure This can be your difficulty, Specially via the internet, And that i hope it isn’t — but I would have it checked out skillfully.
What I’d do is head out and begin screening the TCCM and connections (For those who have that functionality). I undergo a substantial amount of it During this submit.
Bob B states: April thirty, 2008 at eleven:33 pm Hi Kyle……..you've got a wonderful website and possess examine nearly every product both you and your readers have challenges with but my wifes truck has the Grand Daddy of problems and if you inform her to offer it she is going to comprehend. In this article goes….I was permitted to push her around the other working day Once i listened to what I thought was the blinker heading and tried out repeatedly to terminate the non blinking lites without accomplishment. Just after a couple of minutes the company 4 whl drive lite came on, once we parked I questioned if this experienced transpired ahead of and she or he said Sure on a regular basis nonetheless it goes away After i park.
You furthermore may want to check the wires in the encoder motor as they are subjected to The weather and *could* be broken by something flying up less than your car (unlikely, but probable).
, The vac hoses run less than what would looks like a distributor cap. This seems to be in which the working motor sound emanates from, but I'm able to,t reach less than there much ample to check for breaks while in the vac strains. Am i able to securely commence dissembling the ignition process to obtain at lines?
It Appears “electrical” to me… appropriately, the very first put I’d start searching is within the TCCM for corrosion. Then, I’d Check out the schematics posted in this thread and begin in search of sensors.
Rudy claims: March 24, 2008 at 3:38 pm I'm acquiring a dilemma with my 4WD not going into 4HI, I press the button and absolutely nothing visit their website occurs. I put the truck in neutral and strike 4LO it goes in, then I press 2HI and it goes back. Once i have it in neutral and push 4HI both equally 4HI and 4LO lights flash after which you can goes again to 2HI. I read through that for those who jumper pin 13 on the data backlink cable to ground, then transform essential into the ON place the lights within the 4WD buttons flash a code, so I tried it and positive ample a code of 2 flashed meaning motor/encoder failure.
Fundamentally, test Each and every from the lines — Should they be all warm though in 2Hi, then when you try out to alter to 2Lo, one of the traces should really go small (0VDC) — a similar ought to transpire with 4Hi. So, if you try to engage 4Hi therefore you’re absolutely sure There is certainly power at pin 5 (4Hi button sign), and none of the lines modify when endeavoring to transform to 4Hi, I'd personally suspect the TCCM. If your encoder sign line DOES transform, then the transfer scenario encoder motor module is terrible.
Okay, so how the heck am I intending to fix this? I am able to only imaging what GM would desire to do (read as “harness replacement”… $$$$$$$$$$$$$$). And from inquiring all-around about obtaining a substitute plug, my only option will be a scrap yard.
