I wanna fix it if it isn't going to cost me much. Basically the problem is, the air is warm. Doesn't get cold no longer how long I leave it on.

I've read about some recharge kits that that fill the system up, but I'm not sure on what to buy or how to go about doing it. Could something else be my problem as well?

We are having a scorching summer. 35 C everyday...40'* with the humidex.

Cap...

There could be plenty of issues with it. Trust me on this one..mines moody at time.

Does the compressor kick on at all?
Do you have access to a gauge to check the pressure?

It'* true, your first steps should be to test the refrigerant pressure. Buy, borrow or steal a guage and check your pressure using the low side port on the large diameter line running from the accumulator to the compressor.

Also, open the hood and listen for the compressor cycling while car is running and A/C is turned on.

Let us know what you find.

Well, I went to part source and the guage was $40.00, not to mention the recharge kit was $99.99.

Sooo, I went to Canadian Tire (I know, I know...but I figured they could handle it). They charged $39.95 to inspect the system and look for leaks, and $149.95 to recharge. So they inspected it, said it was fine except the system was empty. So I had them recharge it.

An hour later my A/C is as cold as ice, and the best part is the clerk forgot to charge me for the inspection. So I only paid $149.95 + tax. I've been ripped off my Cdn. Tire so many times, I didn't really care.

Anyhoo, my only question is how does the system lose all of that 134 if it has no leaks?

P.*. Something was on sale at Cdn. Tire. See Your Ride in the next few days.

It usually doesn't magically just vaporize...

Good luck in a few days to a few weeks.

Was this on the '96 or the '89?

While it'* true that they don't just empty out normally, your circumstances could have been that you were slowly losing charge and reached a pressure that was too low to turn the compressor on. That is not uncommon. When CT said it was "empty" that may have been a figure of speech.

Now, an older system that has not been used for a year or a long cold season can experience faster discharge than is normal. When an older system is not used every so often, seals and o-rings can dry out, allowing faster refrigerant loss.

If CT tested your system and said it was OK, they have a legal responsibility. They are not supposed to refill any system with a leak that is above a certain measurable rate.

Regarding the inspection charge, many places (if not all) down here will waive the charge if you do the repair right there at their shop.

DO keep an eye on your sytem though, just in case.

Thanks for the info. This is the 96. I do know the A/C hasn't been used at least since september of last year, because thats when the last owner had the car. I purchased it in January 2006, and didn't try the A/C until maybe June, so it has been through one winter.

If it fails on me within a few days or weeks, I will open a can of bitch on Canadian Tire.

It will leak out again. The only way it leaked out to begin with is with a leak in the system somewhere. Take it back and have them put in a UV dye, drive the car for a couple days, then take it back and have them check the car again. I guarantee they find a leak somewhere.
