My '91 nissan nx has a/c when I start it and while I am driving around
it shuts off. The next time I am in there driving around again it is
cool, but then again shuts off. The fan continues to blow, but the air
is warm.

What is up with that? Baffling.

Mike

It ran out last year, and early this summer I had some more freon put
in. I'd say it was charged about 2 1/2 months ago.

Compressor is cycling. First check the wire to the clutch. If that is okay,
check the charge. If the charge is okay, there may be a restriction (clogged
orifice tube, clogged condenser, etc) sending the high side pressure through
the roof and/or pulling air into the low side. Go to forums at
www.aircondition.com for better help :)

Check to make sure the wire is not shoritng out and has a good
connection?
