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.)

It sounds like you're low on Freon.  The compressor kicks in, pressure
builds on the high side and drops on the low.  Low side hits ~25 psi
and the low switch opens to shut off the compressor since it's "out of
freon."  Pressure equalizes and it comes back on when it reaches the
reset pressure of 50 to 60 psi.
