Maintain your eyes on eBay — I just saw one particular Opt for $one hundred thirty five that a guy bought brand-new six months ago and it is scrapping the truck. You can find them at the Chevy seller, but They are really correct around the $five hundred mark — ouch!
Thanks for getting my account Doing the job. I still can’t work out ways to upload an image. Anyway, wonderful site, really useful. Like most right here, I’m obtaining an issue with my 4wd on my 2000 Blazer. I do think it's some thing to carry out Together with the vaccum, but I’m unsure (been much too cold out doors to essentially enter into looking). Confident would like I could look for a vacuum schematic.
I have a heater problem that I think is tied to the vacuum program. Once the truck is warmed up, below 40mph, the heater blows cool air, then at highway speeds it’s hotter than blazes! any feelings?
I pulled in excess of and checked the fuse — everything was fantastic there, but I decided to adjust it just in the event that. However nothing. Following striving every little thing I could consider, I just experienced to manage it and go on on in two wheel push.
Hmmm… it’s hard to say — it could be so simple as the encoder motor signal lines remaining corroded/harmed (Test the schematics in the initial post), or it may be the transfer scenario alone. If your lights get the job done as they must, then this tells me the 4WD system is participating, accomplishing what it should. I think the transfer case is not shifting effectively. As I reported to a poster higher than, it could be time to possess your transfer circumstance checked by a tranny shop.
So, I've every little thing Functioning… time for the new glue. I put a dab of glue down the best of pins #1 and #6 to hold them set up, Enable it set and attempted to pull them out.
sure sufficient the vacume line was poor via the valve go over. I very first adjusted the vacume switch on the transfer case but it absolutely was only $16 And that i never ever have to worry about it once again. So for $26, as well as vast info on this site, I used about 2 hours to acquire it Operating. Can’t thank you adequate.
i read a little something earlier mentioned concerning the manner forks remaining produced away from plastic and sporting out making it possible for the gears to float…and another thing about GMs structure flaw… how do I am going about looking at if there was a remember or something so i could possibly get my pos fastened. us mountain boys up listed here during the do want all four weels turning at once. specifically in the course of this time of 12 months.
Consider the schematic “front axel change & pcm.jpg†— then have An additional think about the wires over the TCCM (Transfer Circumstance Handle Module), Situated under the passengers kick panel.
Can be a TCCM difficulty, encoder motor dilemma or a problem in your transfer circumstance — all of which has been lined here.
I cleaned the TCCM contacts, then was capable to listen to it click, but alas, the four Hello and four LO lights flashed After i attempted to engage them. Rats! Phase two, checked the many fuses.. All OK, then observed a broken actuator vacume tube broken near the actator by itself.
Imagined I'd Provide you with an update on my 4wd situation. As I indicated in my authentic post, I had a vaccum line unfastened. I assumed it went to the canister during the fender, what’s a lot more, I believed it experienced one thing to accomplish with my 4wd not Functioning. Very well, which was the case. I found the attachment for that line within the canister. I obtained a completely new vaccum line (the just one I had was weathered), mounted it and hooked it up on the canister. Then I went You can try this out to the muddy spot inside of a sub-division close to mine, drove into the mud in 2wd. I just sat the spinning the rear wheels. Then I pushed the 4HI button, the light flashed for the next, then arrived on sound.
No, I don’t have something AFAIK — but I do Have got a buddy which includes the All-Knowledge process and might have it (he printed out some great schematics for my TCCM yesterday) — I’ll check with him today and if so I'll write-up it right here for you.
I used to be tempted to just manually sign up for/unjoin the vacuum strains until finally Christmas personal debt is paid out off, but I truly feel obligated to allow them to finish the maintenance since the pushbutton is in.
