[Vwdiesel] AC intermittent

[Val Christian]

On my 91 Jetta, the AC has become intermittent.  The fans come on alright,
but the compressor is intermittent.  Power going to it shows to also
be intermittent.  (Knuckles got kissed by the cooling fan.  Ouch.)

I checked the connectors, and have started checking the switches (pressure
and the like).

If anyone has found a failure mode like this...well, I'm looking for hints.
Meanwhile, I'll keep probing, when it decides to not work.  The meter is
in the car.  But I'm not driving the car much.  My son has tried to take it
over.

Thanks.
