1995 Saturn SL2 How to reseal?

First of all you don't just seal a/c you have to see if you have a leak and if you do then fix what's leaking. When you charged your a/c was it completely empty?How many ounce's did you charge the system with?Did you check your a/c fuse to see if it was blown?When you were charging the a/c could you hear or see it leaking from any where?Let me know.

If they were 12oz can's that would be about 15oz's.A empty system will hold 24oz's the problem is you didn't know how much was in the system when you charged it. So you could have too little or too much charge and the a/c doesn't work real good with too little or too much charge both will cause the compressor to cycle on and off or just not come on at all. So first thing I would do is make sure the a/c fuse is good and make sure you have 24oz's in the system and go from there.

There really isn't a cheap way to tell how much is in the system the a/c machine's are expensive. They do sell gauge's that hook up to your a/c and tell you if there over or under charged by the pressure in the system.I don't know how acturate they are never used one. You could try one of those.

Did you get the gauge that say's too much charge And not enough charge in the system?There's no other place that hold's charge. If it say's too high of pressure and the a/c compressor wasn't on then sound's like you have too much charge in the system. Let me know.

If your starting with a empty system then put 24 oz's in and see what happen's. If it still doesn't blow cold and the compressor is running then you will have to rent a set of gauge's and tell me the high and low pressure's. Let me know what you find.

If the compressor is running and the pressure get's too the high/low switch will turn the compressor off. As long as your charging on the low side of the system which those can hose's only fit on the low side you will be ok.
