Nissan Altima: Air Conditioner problem '99 Nissan Altima

You need to hook this up to a gauge set and stop guessing if it needs
refrigerant or not. You may have it overcharged now and the high limit
switch might be keeping it from running long enough to get cold. It's
R134A you put in there, not R12A. At least I hope so

Evacuate the system to -29", see if it holds a vacuum overnight. If not find and
repair the leak. If it holds, recharge with the correct amount of oil and the
right refrigerant R134. Or take it to someone who knows what the fsck they're
doing and pay them to do it right before you ruin the compressor or the friggin
thing blows up in your face.

When a refrigeration system is evacuated is the oil removed along with the
refrigerant, moisture, etc.?

Thank you.

might be just a very little oil loss with the evacuation process but
the bigger problem is if there is a leak then you can lose a
substantial amount of oil. If you see a lot of oily dirt on your ac
parts or hoses then check there first for the leaks.
Any time you need ac work done you should really have someone that
knows the trade to do the work because you can get some bad injuries
if not done right not to mention the high cost.

Almost anything produced after 1995 is R-134a refrigerant. If you are
putting R-12 then you have mixed the gas and could be creating your
own problem. It could be the high pressure switch kicking out the
compressor like was stated before and hooking up a set of gauges is
most deffinately the way to go.
Also it could be possible it might be a deffective thermostat but the
refrigerant high pressure is the most likely.........On Mon, 28 Jun
