I have a 2000 Suburban and have a problem that we see on long winter
trips at highway speeds. The heat works fine and blows hot everywhere
it is supposed to, but there is a major leak of cold air that is
leaking into the lower potion of the dashboard/kick panel on the far
right side of the car on the passenger side.
The heat comes out of a duct on the inside (left) side of the
passenger's feet. At first I though my wife was imply having one of
her "cold" issues but when we switched drivers and got moving I found
that there was indeed a problem. I can not locate how or where it is
getting in. I shoved a blanket up inot the underside of the dashboard
to try and cut down on as much of the air.windflow as I could, and it
hlped to some extent, but it was still cold.
I took it to the dealer this past week and was told there is nothing
wrong, and that the air intake in on the top in the cowl. I just
looked at the truck again and it sure looks like there is a motor down
on the far right side, up againt the outside of the right fender. I
know GM has liked to draw fresh air in at this location in the past.
I seem to hear a diffeence between re-circulatre and fresh air. Maybe
the damper is moving but somehow letting fresh air inside no matter
Since the dealer had no answer and basically looked at me like I was an
idiot, I gifured there might be an enlighten person that has seen this
problem or may have had the dis-pleasure of tearing out the dshboard
and remembers seeing an air intake on the far right side of th
Any help would be greatly appreciated.
