My 07 Equinox has no heat. Dealer has had the vehicle for 2 days and says he doesn't know what the problem is. His original diagnosis was faulty vent motor. Not the case. The car temps up so its not an engine issue or thermostat issue. We just can't get warm air into the cabin. Has anyone heard of this before? This vehicle also had a defective turn signal. Talk about problems with foundational items which shouldn't break... turn signal and heat!! Dealer is contacting Chevy technical assistance. Any ideas? Thanks.

Sorry team. Typo. It is an 06.

I have the same problem with my 05.

So, what happened next?

Hey, I had the same problem in my 05. It is the heater core that failed I have talked to others who had the same problem and it was the heater core as well in there cases. I work at a Pontiac Buick GMC dealership and even with my discount its 1300 dollars to replace it and you have to take apart the entire dash to replace it yourself. Hope this helps.

Before you take the dash apart pull the heater hoses off the heater core and back flush the system and see if that helps
