This in my '02 Blazer ZR-2.. I took it to a Chevy dealer and they fixed it.. they said it was a motor.. That was a few weeks ago.. Just tonight it goes out again! What do you think could be causing the problem?

 

If your talking about the blower motor the harness could be bad....mine went bad and i had to splice in new connectors.....the tell tale sign for me was it would come and go with bumps in road ...and i could wiggle it to get same failure.

 

That's sucky news.. lol.

HOLY **** I JUST NOTICED YOU HAVE ZR-5 RIMS!

 

That seems to be my problem.. On the way to work today the defroster was working again.. on the way home it quit again.. How do I get to the wiring harness?
