Climate Control Head

[Harry R Glesner III <hglesner@ast.lmco.com>]

Hi Gang:
    As you more than likely remember I've got a '91, 90q20v. I took her by the 
dealer this morning to have the climate control system looked at. The only 
problem it has is that hot air isn't coming out of the center dash vents while 
on "bi-level". They have tested the system and reported to me the climate 
control "head" the thing with the buttons/LED read out is not sending a signal 
to the flap control motor. 
    As back round info the previous owner was one hell of a smoker/pipe that is, 
the car smelt of "rich" pipe tabacco, when I first got it, and when I installed 
the CD player, which I placed the controler in the ash tray (a much better use) 
I discovered what must have been an entire box of used wood stick matches. So 
I've come to think that all of that smoke and fumes went straight up into and 
around the climate controler, I know smoke is fine particals of the 
burnt/burning matter, could I have the controler "gummed-up"?
    I remember someone on the list talking about "cleaning" the contacts? How 
and were are these contacts.
