BTW, the car is a 1990 200 10V Turbo.
Well, I checked the thermo switch located on the radiator.  It checked out 
ok.
I checked another thermoswitch where the upper radiator hose connects to the 
engine block.  Checked out ok.
I checked the two relays in the relay box and they were fine.
I then checked the third relay in the aux. relay box and it checked out 
fine.
There are 3 black wires coming off of the radiator fan and one brown wire. 
 The brown wire should be wired to the third relay in the relay box.  I 
ohmed out that connection and found it was broken.  I had already spent four 
hours on the car and was ready to have the dealer diagnose the problem.   I 
didn't have any more time and/or patience to try to find the break.  I 
wasn't even sure if I was reading the wiring diagram correctly.  On top of 
that, I got a mean case of poison ivy this weekend and trying to work on the 
car with poison ivy was difficult at best.  I took the car to the dealer.

Sure enough - after 1.5 hours of labor and no parts - the dealer found a 
broken wire and charged 62.00.  I feel lucky.

The other problem I wrote about concerned my radio being in 'SAFE' mode. 
 The factory radio has been replaced twice and each time the dealer printed 
the code on the receipt.  I never received another card with the code on it. 
 When I went to program in the number I was using the code from the first 
replacement radio instead of the second.  It finally dawned upon me what I 
was doing wrong.  I went to my Audi receipt folder (getting thicker all the 
time) and found the receipt with the correct radio code.  The radio works 
fine now.

Two problems - two solutions - total cost: $62 - probably about the cheapest 
this car will ever cost me.
