1995 BlazerLT, 4x4, 3 button, 233 transfer case.
So I finally got time to put in a new (used) Transfer case motor, all numbers that I could find match up with my old one.
Guess what, it didnt solve the problem.
Heres whats weird about this. First off I have never gotten any codes from the TCCM. The very first time I pulled the codes I had a code 1. Then I cleared the codes and have never gotten another code at all.
Second thing is, with the old TCM when I hit the 4hi button the light would start flashing and I would hear the relays click 5 distinct times. After about 30 seconds the light would stop flashing and it would return to 2hi.
With this new motor, that Im told worked fine when removed, the 4hi light flashes for only about 3 seconds and I only hear 2 relay clicks.
I know for sure, with either TCM I dont hear any noise at the transfer case at all. I also know that the vacuum never gets sent to the front diff actuator.
I also know that the front drive shaft is not engaged to the transfer case.
Can someone tell me were exactly the TCCM is located on my truck as well. I looked behind the right kick panel and its not there.
If anyone has any information please feel free to put in your

.
Even if you dont think its gonna solve the problem post up anyways. I have to get some ideas on where to go next.
