I'll bet your problem is due to the C/C recirculate door being stuck in the
recirculate position ... we had this problem on our '88 5kCSTQW as well. The
problem is due to a seal moving and exposing some adhesive that eventually
ends up fastening the door in position. When the vacuum motor attempts to
set the door to allow fresh air in, but the seal is so tight that the mount
breaks before the door opens. There is an Audi tech bulletin on this pro-
cedure, and it isn't *That* difficult one at that. The new mount is made
out of metal as well. As I recall I posted the procedure earlier this year
... found it (2/23/95). I've gotta run so I can't proof things well, but
read this over and feel free to ask any further questions ... Oh yeah ... I
did have a similar problem when the engine water thermostat broke in the
open position. I was on the freeway when the temp was below freezing ...
the engine temp went all the way down below normal operating range and the
heater didn't ...
