I am tremendously indebted for you. My new wife’s 2000 Blazer missing her 4wd a calendar year in the past. SHe identified your Website about the TCCM module corrosion, printed off the knowledge and her mechanic fixed it. He was also impressed.
Each and every car or truck I passed while in the ditch, I just saved praying my four wheel push would come on… but no this kind of luck. The actual pisser here is, I attempted it that morning and all was fantastic… now, when I would like it, almost nothing!

Absolutely sure want I could find a vacuum schematic.
My initially problem would be, What exactly are the lights over the dash performing (the 4wd pushbuttons)? And next, what calendar year of automobile are we conversing? (I’m also assuming we’re nonetheless talking about a Chevy Blazer.)

). Of course, most of the earlier mentioned “testing” on the TCCM might not be possible for you personally. I comprehend it’s a challenge which i wouldn't choose to tackle as I do not have access to a different TCCM, so it tends to make like tough. Amongst my hobbies is electronics design and style and programming — so, if it were being me, I'd take the schematics (all schematics are in the main put up of this thread) and start “probing” the TCCM to find out what is accomplishing what. I would report that information, and after that do the exact same process the subsequent time I'd the challenge to determine what has modified. It may well not support you actually deal with the condition, but it really will help you obtain it — as soon as it’s found it might be mounted.

The 2 massive orange wires are your +12VDC strains and so are controlled within the 10A fuse situated in place #15.
goes into store this week..just questioning if it is a linkage of some type? it's possible u joint? The lights shows that the change into 4Hi is comprehensive and four car also..but just no traction from front wheels..maybe a transfer circumstance concern?
If there isn't any connector, like I describe, You then are likely to have to have A further set of schematics, and somebody aware of that method.
