Hello,
I have a Problem with the 4WD on my trailblazer from 2002:
After having changed the front hub, I had the ABS light on: the connector from ABS had a bad connection. after having that corrected, there was no more light on the 4WD switch.
When turning the key on, the transfer case symbol does not light on the dash with all the other lights(ABS...)
I am now stuck in 2WD.
I checked the fuses they are OK (under the hood and under the rear seat).
I think I might have to change the TCCM, but what I don't understand is why the service light on the dash does not enlighten at all.
Last question: if I buy a used TCCM, is reprogrammation needed or is it plug and play? As i live in France, Chevy dealers are not so easy to find.
Thanks in advance for your help
Guillaume
