I wouldn’t endorse driving it for long durations, Primarily on dry pavement if it IS in 4WD however — it is incredibly hard on the drivetrain / 4WD procedure.
As for that encoder motor being fried as the TCCM “bought corroded and shorted it out” — yet again, it doesn’t appear more likely to me. You will find (off-the-leading of my head) seven wires among the TCCM plus the encoder motor. two of these are electrical power (+/-) and so are FUSE guarded. 4 of them are signal strains and the final a single is sign ground. If the bottom wire was corroded and shorted (to what?
goes into shop this week..just pondering whether it is a linkage of some type? it's possible u joint? The lights shows the change into 4Hi is finish and 4 vehicle also..but just no traction from front wheels..perhaps a transfer case challenge?
com and even acdelco.com . No person is listing a module associated with four wheel drive or transfer case. If anyone can assist with a provider of the portion, you should email me at WeinCellar1811@aol.com . Thankyou, Dale
As for the vacuum change you linked to previously mentioned — could really properly be the issue. For $18.95, it’s cheap to discover! Having said that, for pennies it is possible to test it — NAPA (and possibly Some others, like PepBoys, and so forth.) should have vacuum hose connectors — male to male connectors will help you to adhere 2 vacuum strains jointly.
That’s odd that The sunshine will arrive on instantly, devoid of flashing and without the need of partaking the 4WD. The good mild coming on at 4Hi is generally an indication which the system is functional.
What I would do is examination the button assembly wires with the TCCM. If I’m not mistaken, I feel that the buttons are pulled substantial (+5VDC) and ground out on pressing them (I may be wrong, so be sure to double Examine!). So, I’d exam each among the list of button assembly wires in the TCCM. The must all be the exact same with no buttons pressed.
I discovered a forum where a guy had a problem where his 99 Blazer would not change to 4HI. When he pushed the 2HI button, The sunshine flashed but almost nothing happened.
Maintain your eyes on eBay — I just saw just one go for $135 that a guy acquired brand new 6 months ago and is also scrapping the truck. Yow will discover them within the Chevy seller, but They can be ideal around the $five hundred mark — ouch!
Dan states: December seventeen, 2007 at eight:33 am I have a ninety nine′ S10 Pickup and 4wd functions fantastic however the front drive shaft is not going to disengage from your axles when switched to 2wd. Generally the transfer scenario is switching from 4wd to 2wd but the front axle is usually engaged. I traced the cable cable again to your vacuum actuator below tha batery and found that the cable isn't certain up though the actuator alway has vaccuum to it Irrespective When the auto is in 2wd or 4wd.
How to check When the change is bad? I’m unsure which swap you’re referring to, but no, I usually do not. I’d just Google it most of the time to locate what I’m searching for. Every little thing that I ever wanted to take a look at was identified via Google.
Initial, be sure to note that I am NOT a accredited mechanic! I like auto get the job done and do nearly all of my own function, and so gain the knowledge which i share in just my blog site. Okay, so adequate with the disclaimers by now!
I'm able to below the encoder motor activating and deactivating. I wonder Should the mechanics did a thing towards the transfer scenario for the duration of rebuilding of the transmission. Anyway, what can be earning this hissing seem in or near this transfer case.
