Default 96 Camry AC problem, intermittent

My 96 Camry is used by several in the family. At first I heard that the
green light for the AC wouldn't light and, of course, no cold air. Then the
light was on and AC working fine. Then, light on, fans working and no cold
air! When I had a chance to look at it, the green light wouldn't come on at
all during a couple hours of working on it. All fuses checked OK.
But now, for the last 2 days, it's all working fine. This tells me that the
freon and all that is OK, but it seems a switch is intermittent. Has there
been any intermittent problems with the AC panel switch? I've taken it out
and sprayed inside as best I could with contact cleaner and it's still
working fine.
Aren't intermittents fun?

TIA,
Gerry

Not necessarily. Freon is a gas and expands and contracts with
temperature. I think if you track the temps, you'll find it is working on
cooler (?) days? This is a guess, and educated one based on a car I had a
few years ago (Corolla) I'll bet the freon is low and needs a recharge.

Take it somewhere, don't use those suicide cans...

I took it to a shop I respect today. A man's gotta know his limitations!
Thanks

Guaranteed, you need to charge your freon. Of course you probably
already know this now that you took it to the shop.

That's what it sounds like. The car is rarely used, it's kind of a spare I
keep around and it has sit for months at a time. They're going to look at
it tomorrow. Stay tuned.

Yes it does contract and expand, but it is more likely to work on a hoter
day. When it's freon is low and the ambient is low, it will not work, as
there is a sensor (compressor will not go on). When temp goes up, freon
expands an the compressor may go on. It still will not cool well.

Only if you don't know how to use them!

Rich

PS Had a similar problem. Adding freon worked. Also have it checked for
leaks. Most places will not add freon, unless they fix the leak. In my
case, there's a very small leak from the schrader valve on the high side.

Does the Camry have a too hi or too low,. head-pressure switch, for the
compressor clutch?
