I have been following the threads about non-working defroster on 2001-04 Chevy Monte Carlo's. I have traced my problem down to the Radio Antenna Module. Unfortunately this part GM# 10289183 is discontinued without replacement. I found 1 at dealer in state of LA but he quote "doesn't ship parts".


Is there anyway to bypass the defroster side of this module to allow defroster to work. Radio side seems to be working fine.

 

Before going down that road, I am assuming you checked the hidden circuit breaker? If not, check this thread:

Outside of that, I would recommend contacting Zspot. He might be able to help source a replacement part (he works at a dealership and has helped me a few times). See the thread link below:
