Subject: <'90V8Q> AC Questions

Hi Audi Fans:

I am having a problem with the inside of my windows fogging up so badly 
that I have to wipe the windshield with tissue and run the defroster on 
high fan and temp to get a big enough clear spot to drive.  

It was rainy here in the Denver area yesterday but it's not that normal 
so my problem/question doesn't come up often.  When I left work, it was 
cool and rainy but no fogging.  My wife and I went out to dinner and I 
put the climate control on AUTO and MAN! did it fog up fast.  Made the 
drive to dinner an adventure plus made me cranky about my (originally) 
expensive German car.  Subarus were driving along with nary a wisp of 
fog on their windows.  My fellow German car enthusiast (WMB 6M) at 
dinner thought maybe heater core or fresh air/recirc flap (is there 
one?).  There is really no control on the '90 climate control for 
recirc. Just AUTO or BI-LEV to kick in the compressor.  When I did that, 
even with the temp on LO, it didn't seem to get cold and dry air from 
the vents.  This AC works great during warm weather BTW.

Any IDEAS???  I am driving to Massachusetts next week as we are moving 
there and I have a feeling there may be more humid rainy days there than 
Colorado.

Also, rear window defroster has always done nothing.  Dealer: "They just 
don't work very well".  I mean there isn't even a hint of cleared glass 
around the filaments!?!?

Sorry about the bandwith...TIA for your help.

With respect to the rear window defogger, it should at least defog.  
(Don't expect ice blasting ala a Taurus windshield.)  The Bentley 
manual describes a set of tests for the rear window antenna amplifier 
mounted in the left D pillar.  These tests are mainly of the power 
connections to the defogger.  They will reveal if you are getting 
power and if current is flowing to ground via the window heater wires. 
 Note that the window ground connection is on the right D pillar under 
the trim.

Your ac problem may have many sources; I'm too new to these cars to 
speculate upon them all.  However, the air path design shown in the 
Bentley manual suggests that the water condensed by the air 
conditioner puddles in the system.  I think that is why I get a swamp 
stink when I use the air conditioner a lot and then the car sits for a 
day.  I was going to pull the fan motor and check that area, but a 
recent posting here on the motor interference fit with the dash has 
fazed me a bit.  Does anyone know if there is supposed to be a drain 
that could clog?
