My two wheel drive would have interaction although not my four. I examine the tccm and also the vaccum swap and also to my particular amazement the vaccum line had broken from the change. I mounted this challenge and now my four wheel drive is working yet again. The data you posted saved me a trip to the supplier!!!
Once i get much more time, I’ll tell you about all another things that have long gone Erroneous with my Blazer Considering that the working day I drove it from the large amount, with twelve KM on it. It is, as so a number of other blogs I've read from Blazer proprietors on the internet, the Tale of a lemon.
As I've said often times in the a few webpages of this write-up… every thing which i understand about the Chevy 4WD process has long been posted right here. I have no more info to supply. I'm not a mechanic.
Greg states: November 27, 2007 at 12:fifty one am Many thanks for the great pointers. I used to be equipped to determine several of your a lot more primary guidelines and confirm that my entrance generate shaft is turning while in 4wd but not in 2wd. So far so excellent (It appears to me), so I’m investigating utilizing my newfound knowledge re.
Believed I might Supply you with an update on my 4wd problem. As I indicated in my initial post, I'd a vaccum line unfastened. I thought it went into a canister within the fender, what’s extra, I believed it had something to do with my 4wd not Operating. Perfectly, that was the situation. I discovered the attachment for that line to the canister. I acquired a whole new vaccum line (the one particular I'd was weathered), mounted it and hooked it up into the canister. Then I went to the muddy spot within a sub-division beside mine, drove into the mud in 2wd. I just sat the spinning the rear wheels. Then I pushed the 4HI button, The sunshine flashed for any next, then came on solid.
In the event you don’t intellect, I'd greatly prefer to article your feedback — if you want, I'm able to leave your title out — obviously, the choice is yours and I will regard any selection you make, just allow me to know.
What I’d do is head out and begin testing the TCCM and connections (In case you have that ability). I endure a large amount of it During this article.
John Boy says: December four, 2008 at 7:19 pm You're a hero to A lot of people! Looking at your weblog it seems you have saved men and women hundreds if not 1000s of bucks by aiding persons fix their 4WD challenges by themselves. I solved my challenge after looking through about vacuum leaks. Sure sufficient the vacuum hose had damaged off the activate firewall. It seems the hose was also small to start with and was kinked resulting in it to are unsuccessful prematurely.
I ment to say, I'd my transmission rebuilt two months back as well as the 4wd worked then. I put my Blazer on jack stands and started tracing the hissing audio (air leaking?). I’ve discoverd the hissing noise is coming from the transfer scenario.
It appears like the gears are participating while in the transfer case but I don’t listen to the actuator participating along with the lights over the sprint don’t arrive on. Any solutions?
should i be unplugging my tccm and resetting the method right after i modify to encoder motor. I believed it had been a transfer circumstance proplem because i thought it had been binding up and not allowing teh encoder motor begin in 2wd.
DISCLAIMER: You should Take note that I have stated various times that I have not tested any of what I have explained below — I'm simply just considering the challenge logically whilst investigating the procedure schematics. Take a look at ALL WIRES ahead of applying power to them.
So, devoid of bodily eliminating the encoder motor module and manually shifting the Transfer Scenario into 2Hi, unfortunately, it’s caught in 4WD until you may get it into a mechanic.
