Hot air coming from winshield section while driving.

[DynoXG]

While I'm driving, hot air comes out the air ducts in front of the windshield and side vents. When I slow down or stop, it stops. The faster I go the more hot air that comes in. Any ideas?

First guess.
Vaccuum leak on one/more of the vent flappers letting in outside air.

do you have the climate control with the knobs or the one with the buttons

I looked everywhere and cant find any vent flappers. Where are these?

I have the climate control with the buttons, not the knobs. Thanks.

I'd check for leaks before I went digging around for these.

These are great. Thanks StrictlySpeaking. I'll dig into each one and do them one by one. Hopefully I'll see something that's wrong.
