Question about 2002 Chevrolet TrailBlazer
SOURCE: Service four wheel drive
Without further diagnostics, it could be any # of causes, but these are notorious for bad conections at the transfer case encoder motor and /or the encoder motor itself.The motor,when replaced may need to be reprogramed.Be sure the switch and wiring are functioning properly as the encoder and/or related control module are pricy$$

I would first give a visual test on the wires to see if there is a short anywhere, can you run a test meter on the control module to see if there is ohms resistance or shorting out!
Hope this helps.
contact again if you cannot sort this out!
