With no understanding what is happening using your controls, I don’t know what more I can offer you. If your controls work, and you also in this article the Transfer Scenario Handle Module (TCCM – the module beneath the travellers kick panel!
Once i get much more time, I’ll inform you about all another things that have absent Erroneous with my Blazer since the day I drove it from the ton, with twelve KM on it. It is actually, as so a number of other weblogs I have examine from Blazer house owners online, the Tale of the lemon.
I've a heater situation that I think is tied on the vacuum technique. After the truck is warmed up, less than 40mph, the heater blows cool air, then at freeway speeds it’s hotter than blazes! any views?
My two wheel travel would engage although not my four. I examine the tccm plus the vaccum change also to my specified amazement the vaccum line had broken off the swap. I fixed this difficulty and now my 4 wheel travel is Doing work once more. The data you posted saved me a trip to some dealer!!!
As for the vacuum change you associated with earlier mentioned — could very nicely be the issue. For $eighteen.95, it’s cheap to learn! Having said that, for pennies you can take a look at it — NAPA (and probably Other people, like PepBoys, and so forth.) should have vacuum hose connectors — male to male connectors will assist you to stick two vacuum traces together.
Replaced the fuse and right away blew all over again, I used to be trapped in four-hi. Arrived house that night time, tapped around the transfer circumstance and encoder motor with a rubber mallet, changed the fuse and 4wd worked. Set truck in two-hi and no noise. Started out the truck yesterday and the fuse was blown again. Last but not least went and acquired an encoder motor and replaced it this morning. Now absolutely nothing seems to function but TCCM(which looked as if it would function good before). Press 4-Hello button, and TCCM clicks about five occasions, then defaults again to two-hi. Exact issue in four-lo. After striving this about five occasions, it received’t even seek to go in 4wd, just clicks and stays in 2-Hello. Pull battery and it resets but goes again to a similar problem. Remeoved the Encoder motor and reinstalled, no luck. Any Suggestions?? Do you think that I acquired a foul encoder motor from areas retailer? I don’ty have sufficient hair as it can be, I don’t would like to pull far more out. Many thanks.
You could also unplug the TCCM and faucet around the encoder module to view if it may be stuck (a heat garage wouldn’t harm possibly!) — go away the TCCM unplugged for a minimum of two minutes, then plug it back again in. Then, turn The crucial element on to off five times, then to on and try it.
You understand, aside from what I’ve posted higher than about the forks/gears, I don’t truly know Considerably about them — I'd the problem discussed to me whilst I used to be driving dwelling to the freeway in hurry hour targeted visitors. I in no way really questioned any thoughts even more than that — ’result in my 4WD labored!
Hold onto that imagined for a few days — some computer software is on the way in which that will permit me to retrieve the information.
I eliminated the battery tray identified the diaphram and it is Performing. browse could my trouble be vacuum? I guess I didn’t seem tricky enough because I didn’t begin to see the vacuum switch by distributor and it’s fairly tight in there . Any suggestions? Thanks,Tim
I cleaned the TCCM contacts, then was able to listen to it simply click, but alas, the 4 HI and four LO lights flashed After i attempted to engage them. Rats! Action 2, checked many of the fuses.. All Alright, then found a broken actuator vacume tube damaged near the actator by itself.
Hmmm… may be several things. Initial, if you can obtain into 4Lo, issues almost certainly aren’t as lousy as they appear — this, in essence, informs you which the components in the process are Operating.
PS – I actually hope I’m not way off foundation in this article and sending you on the wild Goose chase, but it really’s difficult if you can’t begin to see the automobile.
