[s-cars] climate control issues

[ron kirkham]

So my '93 S4's climate control is now fully whacked and needs some work.
For several months now, the CC head (with temp display side burned out) will
indicate that the fan is on full blow, but no blow is going. For the same
several months my ingenious solution has been to open the drivers door and
give it a more agressive than normal close......OK I've been slamming it.
This has broken the fan free of whatever is stalling it, and all is blowy.
Now, this highly scientific resolution has failed also, so it's time to do
something as winter is still going in my world.  The CC head unit
diagnostics are not accessible to me via the standard/understood method, so
I don't exactly know what is up.  I do know that the flap controls for air
distribution have been wonky since I bought the car in '01, and I've just
lived with it.  So now it seems I'll need a new blower motor as well as
whatever other flap motors are non-func.

Questions:  Are the climate control diagnostics only available through the
CC head, or can vagcom get me there?  If I take the CC head out of my '95.5
S6, will all diagnostic functions be equal between the '93 and '95 CC head?
If so, I should be able to figure out the problem(s) no? Then of course I'm
going to need some instructions, (and part numbers?) from some kind
soul that has been in this nether-region of the dash.

As always, any help appreciated.
