Corvette Heater Defrost Fault
Summary of the thread
A 2002 Chevy Corvette is experiencing issues with the heater not producing warm air and the defrost function failing, leading to fogging. The problem is identified as a fault with the defrost air distribution flap, likely due to a bad connection in the HVAC unit. The suggested solution involves checking the cable and plug connections to the flap motor, which is a known weak point. Ultimately, a corroded connector on the flap motor was found and fixed by a professional, resolving the issue.

Good call! Where exactly is that flap motor located? I don't want to start ripping apart the dashboard panel without some guidance! And no, no strange noises that I can hear, just icy windshield!

On my car I found it easier to just take it to the workshop, as I did not want to break any more than I had already. And yes, it was a corroded connector. It's located behind the center console, fairly deep in there. If you aren't comfortable with dismantling interior trim, it's probably best to get it checked out by a professional. They'll have the proper diagnostic tools to pinpoint the issue quickly.

Took your advice and brought it to a shop. You nailed it – corroded connector on the flap motor! 95€ later, and she's blowing hot air like a champ. Thanks for the pointer; saved me a ton of grief!

I had a similar issue with my Corvette a while back. Check the cable and plug connections to the flap motor itself. That's a known weak point. Are you getting any unusual noises from the dashboard when you adjust the temperature?
