The air conditioning on my 92 Camry no longer seems to work. I'd
appreciate any feedback on what could be wrong and the cost to fix it.
Thanks

Chances are some refrigerant has leaked out.
System needs to be re charged, and preferably fix leak to avoid
recurrence.
Could be a hose or fitting. Cost depends on source.

thanks

Turn the a/c on with the hood up and see if the clutch engages to rotate
the compressor. You will hear a solid "clunk" if it is working, and you
will see that the whole clutch assembly is rotating.

If the clutch does not engage, probably your pressure is low because of a
loss of Freon. You can force the compressor clutch to engage by hooking a
+12V clip-lead directly to the clutch wire.

With the compressor rotating, look at the sight-gage on top of the dryer.
It usually resides in front of the condenser (in front of the radiator). If
the sight-gage shows a white-cloudy mixture then you are low on Freon. Your
'92 uses R-12, and that is hard to find now that it is illegal to produce
it. There are some substitutes for R-12, but none are the real thing. You
might try to get some "Freeze-12," which I understand works reasonably well.

Assuming you can scrounge-up some refrigerant, you will need a manifold
and gage set to fill the unit properly, but you can fudge it by filling
until the sight-gage clears and then add just a tiny bit more.

Good Luck.

Hello Dick. I have a gauge to go with my new form of refrigerant (not
R-12). It shows hi-side pressure can be anywhere from 25-45psi -
which seems like a big range. Would pushing it to 45 risk a leak?
Not sure how old the compressor/lines are, as the car (230M) had
engine replaced 20 thousand ago - and not sure compressor/lines was
included. Thanks for insight. Tim

Car: Camry 4-cycl, 1994.

I had it refilled last summer and I was surprised that it stopped working
earlier this month. I'm not sure if it's out of refrigerant again, leaked,
or something else is broken. Are there a few steps to diagnose the
problem. When I turn on the air, I can hear different noise like it would
sound when working but just no cold air out. Is it possible that it wasn't
filled correctly that it was out of it sooner than it should?

Thanks for the help,

They should have put in refrigerant with a dye in it so they can tell
where it is leaking , with ultra-violet light.

Do you see bubbles in the sight glass on the drier can?

Like old struts and speakers, by the time you felt it it was bad
enough. These systems typically leak about 0.5 to 1 oz every year. And
that's considered new and "completely sealed." Good thing parts stores
carry $20 all-in-one gauged cans. It's a rough ball-park method so
don't over charge it.

Depending on the system a small recharge every 3-4 years should help.
But if it leaked out since last summer then you probably have a big
leak than 0.5-1 oz/year ;) ;) ;)

liquid to gas and back again. It is not like oil and never needs changing.
It can leak out and you have to add more. If it leaks out quickly, then
find the leak.


I had a new1991 Camry with over 190,000 on it when I sold it in 2007 and
never had anything done to the airconditioner and it cooled the car fine in
90+ deg heat.

I had to replace the expansion valve and seals in my 92 Camry.

The expansion valve o-rings were leaking and you cannot see this as the
expansion valve is enclosed in the expansion coil air box.
I was told this was a common problem with Camrys.

I bought a seal kit and expansion valve at Advance Autoparts and tore into
the dash. Took me about 8 hours.
Replaced the freon and it cools very well now. No more leaks!

It is such a pain in the ass to take apart the dash be sure to have all
replacement parts for reassembly.

Good luck!

Sure, there was a recall of expansion valves in all Toyotas of early
1990s. The defective expansion valves corroded and let refrigerant
out. I would think by 94 these were fixed. Maybe not.

Most owners would probably think that their ACs were just weak after a
while and needed a recharge, instead they were driving around with
defective expansion valves!

Have a look at your sight glass, located on the receiver/drier, to

If it has a foamy or streaky look, the refrigerant is low.

AC Refrigerent (freon) lasts 1,000's of yeras. Barney rubble still has his
original freon, because his AC doesn't leak
YOU have a leak.
