95 A6q AC Questions...

Thanks Tony.
 
The figure with the engine off is the check level of the R134A.  It's  
interesting that they do not have a normal operating range for when the  compressor 
is spinning.
 
I do not believe that it is shutting off due to high pressure or low  
pressure.  next thing to check once I get the pressure within the system  right is my 
mixing flaps.
 
Lots of fun.  I really don't dig these automatic climate  controls.  Much 
prefer the dials.

OK, the  low side should be 26-29, the high side is rated at 79.8 psi
at 77 degrees  F. It shows that with the engine off, though. \not sure
i understand  that.

\one other qwuestion, is the compressor shutting off at all? \or,  is
it running all the time, but just not coming out of the vents  cold
enough. \if the second is the case, you may need an  expansion
valve/oriface tube. \the old one may be plugged.

Another  thing mentioned in it is the belt slipage. \there is a speed
indicator on  the compressor, and if it senses belt slipage it shuts
the compressor  off.
