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.

I've heard that some part of the system (sorry don't know more details) can
freeze, especially in high humidity and when it does the AC will stop
working. Instead of running the AC at full cold, you may try selecting a
temperature setting a little above max cold. If that solves the problem I
would have the pressure of the 134A (I assume that's what you have) checked
and topping it off if necessary.
