Okay I am not sure if this is just my car or all of them.
I am noticing alot of heat coming back into the passanger compartment as summer is coming up on us here in Calif.

I DO know there is NO heat/sound proofing under the colsole, and I know there is a big hole in the console for the transmission shifter.

So the question is, is it just my car that is sucking heat into the passanger compartment? And second would it hurt anything if I were to put down the Dynamax (I think its called that) sound/heat proofing under the carpet/console and Firewall?

 

Regular Dynamat is just for noise reduction. You need the thicker (albeit lighter) stuff with the shiny silver covering which is designed for heat reduction. I bought some for my Firebird from JC Whitney. I think the box says "Insulator II" or something like that.

 

You can get that stuff from Pep Boys for about $20/roll. Works great.

 

Here is an exerpt from the 89 owner's manual page 2C-7:

"Your Camaro has a flow through venteliation system that provides a supply of outside "ram" air into the car when it is moving. When the vehicle is not in motion you can get a steady flow of outside air into the car with the heater or air conditioning blower running."

That was the caption of a pic of the car with arrows showing the airflow coming in (you guessed it) by your feet, and going through the car and out through the vents in the door jambs.

If you have the heat selector on HOT, or your heater by-pass valve is non-functional or missing, you'll feel a draught of hot or warm air while you're driving.

 

Yeah, I got that heat problem too in my 82 z28.
