Clicking new tccm.. good or bad?
I put a refab tccm into my 1998 Bravada. It clicks on startup.. about 3 times. The old one does not. I have no reference to know if this is an indicator of a bad TCCM or a TCCM that won't work with my system
My AWD still don't work. I'm about 95% giving up on it. I have a horrible feeling it's in the wiring behind the dash somewhere. I have another post on what all I've done.

Like I said, I have no reference. Since the Blazer has pushbuttons and multiple settings, I wonder if your TCCM goes through a different series of tests? Remember the Bravada is a no select AWD one speed transfer case.
The TCCM I bought is AC delco 19326776

No it never comes on in any situation. From my previous link, I mentioned I know the LED light works because the previous computer that I was looking at and examining for corrosion, ended up with some water from somewhere (heavy rains) and that seemed to activate the light off and on for a couple days till I replaced the computer. The light had nothing to do with actual functioning of the AWD. The water was making some sort of contact.

The manual describes it as the same case as the astro and i dont think the light is working correctly. If you have access to a Tech II scanner that would help solve things. Ill do some looking to see if I can help more.

I'm seriously contemplating just finding the newest Blazer..2005? and getting one of those. I like the 4 button 4x4, and I'm pretty familiar with the mechanics of that chassis now with all the stuff I've replaced on this Bravada.

Was this system working before the old TCCM got wet ? , what makes you think its dash wiring (just curious), my astro had a broken wire from a rock strike or road debris , it was in the bundle under the drivers door following the frame , I don't think i would have found it without the code that I could read and the test procedure associated with it.
