My a/c when it works is blowing out very cold air (40*), but lately it has
been working intermittently. The first time it went off was after driving it
all day with a/c on. Then after sitting for 24 hours, I started it and the
ac works and it works for a week before it quits again. This time it is
early in the morning with a cold engine. Let it sit again for almost a day
and it works again. Works good for 5 to 6 days now it is off again. Worked
this morning for about 20 minutes and now does not come on. The blower has
always worked. Still cools very well when it works but what would cause
this intermittent situation?

Thanks for all that respond.

One possibility is the clutch relay. You could try swapping it with another
one in the relay/fuse block (next to the battery in the engine compartment)
and see if the problem goes away. On our '96 GC, the black relays in there
are all the same part number, so they're interchangeable.

A similar problem in my old Ford turned out to be the wide-open throttle
relay (it cut off the compressor when the accelerator was floored) - very
intermittent.

Good luck.
