Having problems with your 2002 Chevrolet TrailBlazer ?

Trailblazer 2002, service 4x4 light is on dealer said replace

\015 Transfer case control module and wants 500 bucks. We found a guy that had a damaged trailblazer and we bought the transfer case control module from him and the model number is identical. When we put it in the light for 2hi is on but doesn't do anything else. The service 4x4 light is no longer on either...does this need to be reprogrammed for my truck even though it is not new? Please help I was just trying to avoid the cost of a new module.\015 Posted / edited by AnonymousUser on : 08-08-2022
