Question about 1997 Jeep Grand Cherokee
R134a .. You can buy it almost anywhere, from Walmart to the dealer.

R134 i believe, there should be a stick somewhere under the hood on what type and how much the system takes. Here is a link that may help you recharge you A/C system.

What you will be looking for (in your engine compartment) looks almost like a large valve stem that you would see on a tire. It will probably have some kind of plastic cap on it.
It shouldn't be that difficult to find. You may want to search for an engine compartment diagram for your make/model/year vehicle.

There are special cans of R-134A with dye in them for detecting leaks. Most leaks occur around the fittings near the compressor. Recharge the system with the leak detector can or R-134A. There are also cans of R-134A with an additive to stop leaks. I would use these products to either detect your leak or to stop it. Best of luck.

More likely the recharge blew a o-ring and you have a leak. When your Cavalier was blowing hot air and a recharge fixed it that means it was low on freon which lets o-rings dry out, go back to the shop and have them leak test it. They use a pressurized dye to find the problem. If it's blowing it's not the cooling fan relay, they may have meant compressor relay but I'd have a leak test done first it's not expensive and easier that chasing unknown possibilities.

Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.

SOURCE: 2006 Chevy Equinox A/C freezes
Actually there is a evaporator tempature sensor that has gone bad that is causing it to freeze up like that because it cycles the compressor on and off to prevent this freezup and vwhen the sensor goes badf the compressor will continuasly run all the time. $4e0.00 part.
