[s-cars] Heater control flap motor

[Toborg Michael (AC-SM/ESC5)]

Operate only in the installed position with the controller. 
I like cultivated though, sounds sophisticated.

Hey Jerry,

According to babelfish "Nur im angebauten Zustand mit Steuergeraet 
betreiben" translates to "Operate only in the cultivated condition with 
controller".

I've had exactly the same problem with my '93 S4 for about ten months 
now, but after blowing cold air for quite some time I found that if I 
left the climate control at "HI" I would usually get hot air, so I've 
lived with it this winter.  I have a new temperature flap control motor 
sitting in the basement just waiting for the warm weather and a long 
weekend to install it.

I remember coming across an article online somewhere that detailed 
cleaning/repairing a sticking HVAC flap motor for the S4/S6, but I can't

seem to locate it now.  The gist of it was that you carefully take it 
apart, clean all the crap out (mainly carbon brush dust if I recall 
correctly), lightly lubricate and replace.  Some one else did mention 
though that they experienced the failure again after doing this only a 
few months later, but given the cost of the flap control motor it may be

worth a try.

I'd be interested in any information or pointers you could give me on 
locating and removing the temperature flap control motor.  The Bentley 
CD-ROM I have is not terribly clear in respect to this motor, and from 
the (very brief) look I had under the wiper/HVAC cowl cover at the back 
of the engine bay, it was not immediately obvious how much I had to take

apart to get to it.

Good luck and let me know how it goes!
