Re: AC problem
Pressure switch, low freon level, air door not fully engaging to cool air side, condenser airflow impeded, etc. How long since your last recharge?

Re: AC problem
I have owned the car a year and a half and I haven't had the AC recharged. Should that be the first step?

Re: AC problem
Yeah you have a 94 (R134a) so it should be pretty straightforward, make sure they put in new Schrader valves (like tire stem valves but for the a/c) after they evacuate the system.

Re: AC problem
might consider getting the "O" rings replaced as well while in the system. That is usually where the refrigerant goes if it is low. "O" rings are a nice cheap easy step. to usually prevent refrigerant loss in the future.

Re: AC problem
Bring it in and I'll have a look at it Do you still have those rims? If so I can come pick them up now that you are back in the states

Re: AC problem
You need to measure the refrigerant volume before you haphazardly attempt to add more...
The first thing you need to do is run the self test of the climate control system. It does not require periodic recharging. I have never had to recharge my car, and it just had it's 15th birthday.

Re: AC problem
Refrigerant never gets used, it's like air in a tire. It is inside a sealed system If it leaks out, there is a problem. I recently worked on a customer's camry that had 467,000 miles on it. Compressor was dead but it still had over a pound of 134a in it, factory charge was 1.2 lb.
Using the a/c will not make it deplete, but it can exacerbate a leak because of the pressure increase from it's use. DO NOT charge a car unless you know how much is in it. If you over charge it, you can make the compressor pump in excess of 500 PSI which can cause hoses to explode and could seriously injure you, or even kill you. No lie.

Re: AC problem
is there anyway to tell whether your compressor works or not without having a belt on it?

Re: AC problem
Spin the center part of the pulley by hand, if it does not turn, your compressor is borked. It will turn easily by hand, but you should feel some resistance. No real way to tell if the reed valves are bad without it being hooked up to gauges and running with a belt on it, but if it's seized, you'll know it.
Dave - Thursday works, I will be around, call my work as soon as you can, 754 1515, ask for Dave in Service, basic evac and recharge usually runs about 125-145 or so, depending on the charge needed, assuming it needs a full recharge and not just topped up, if it just needs some refrigerant added, it will be less, but that is your best bet is to bring it to my work. (I might even have a discount coupon I can give ya...)

You could also test the clutch I suppose if you really wanted to. I don't see what that would tell you though. Gauges are really the only way to see what is happening inside the system..
