defroster-air conditioning question

When I'm using my a/c in my 96 coupe,(in Florida most of the time) I get
condensation on the windshield over the defroster vents. There is cold air
coming out of the vents. Is it possible the defroster flap ( or whatever
it's called) isn't shutting the flow off completely when turning on the a/c
and if so, what can be done without completely removing the dash?

Rob, If you have the climate control or what ever they call it there
is a vaccume module. it is controled by the buttons in the dash, the
buttons in the dash send electronic to the elcectronic vaccume control
module, its failed position is defrost. as far as I know it is not in
the dash.

hope this helps.

Rob I have the same problem with my 96 vert. Don't have a clue what the
deal is, but it drives us crazy trying to keep windshield clear to drive.

Any Ideas, add us to the list who would appreciate any ideas.

Chet & Rob,

There is a electric to vaccume control module, when it fails it
defaults to the defrost mode, is is not the buttons in the dash they
are all electronic

I kind of thought that, now the tough question, how difficult is the control
module to get to change? I'm moderately capable with tools if I know
exactly what has to be done, just not a mechanical wizard then
troubleshooting.

I'm not sure I'm pretty good with tools but the clinker is if you buy
the part from a chevy dealer, you are stuck with it if it doesn't
correct the problem. the part was about 900 bucks. alot to risk if
it doesn't fix the problem.
