Lightbulb Heat from the lower vent

Hey guys, Are any of you experiencing heat coming out of the lower vents with the AC and fan off? I noticed going home one day how warm it was in the car and when I felt the lower vent had warm air coming from it. Any ideas?

I'd say it's a leak from your engine bay. This happens in my car and the vents are pretty much all disconnected (no ******* clue why).

bad air mix motor or logicon can also cause that.

Is the air mix motor working correctly when you move the temp indicator on the logicon??

we won't know until he answers, but I doubt you are right. He said the air out of the vents...

And there should be no leaks... make sure you plugged any holes through the firewall when you gutted your car.

Heh, I meant that COULD be an answer. I just noticed pretty much all my vents leaking hot air and basically none of them are hooked up. I'm still trying to figure out why.

I'll check tonight when I move the logicon lever to see if the air mix motor moves. Some thing else to work on...LOL
