FNG from Colorado
About a week ago my 2002 got stuck in 4L so I started searching for hints on how to fix it. This forum came up nearly every time, and some of the best info I found was on here. So I joined, mostly to get access to some schematics.
Figured I should say "Hi" and maybe share a picture taken when I brought the thing home on my birthday last year (I've never owned a 4wd, even though I've been driving in Colorado winters for 27 years). One nice thing about getting old is the ability to buy an unneeded vehicle just because you've always wanted one like that

Now, let's see if I can figure out photos on here

If anyone cares, it was the vacuum line. I spent nearly $400 before finding the hole in a $2 piece of hose.
I keep telling myself that the TCCM would have gone out eventually anyway, but I haven't convinced me yet- Not a speck of corrosion on it nor the connectors, unlike the '03 I borrowed to compare it against.
By the way, the TCCM in a Blazer with Auto4 and the TCCM in one without are NOT interchangeable. That one plug will fit, but then the magic smoke gets out and you're buying your buddy a new part, too
