It is possible that you have a clogged expansion valve or orface tube, you really need to get the systems pressures tested, you can tell a lot about the health of the system just from the readings and the way the gauges operate.

The AC pro recharge is just to add to a system that has some freon in it already from what I read what you wrote your system was completely empty so you are going to have to keep putting freon in until your compressors clutch stops clicking once it stops clicking the system is full so do not use the AC pro just but the freon in the little cans

Buy the freon in the little cans it's cheaper then the AC pro.

tennishoes is right, get a pressure gauge and do it right. Sounds like you have a pretty good leak if your continuing to recharge it. Might be time to have your local shop diagnose and repair it for you. The put dye into the system to find the leak under pressure. I just ended up replacing a hose and accumulator on one of my cars due to a huge leak.

You may also try adding a can of freon stop leak it may stop your leak if it is a small leak. If that does not work time to have system repaired.

It's not Freon Its R134a and here is a chart for Corolla 2003 -2008 click for full screen

Sorry FordNut do not now were you get your information but R 134a is a freon.

The Receiver/dryer serves the same purpose as the accumulator in other cars.

Freon is chlorofluorocarbons. R134A is dichlorodifluoromethane, a haloalkane refrigerant

Fordnut is correct Firebird, Freon is the old R12 used in older vehicles and discontinued in 1995. It's was a registered name by Dupont. Now R143a replaced it as a safe alternative for the environment. Laymen still call R143a 'Freon' but it technically isn't. It's a refrigerant.

Dichlorodifluoromethane is R12 1,1,1,2-Tetrafluoroethane is 134A

I stand corrected tennisshoes, I had part of it backwards. Mixed up. Thanks for the correction.

When I buy a can from the parts store it says R 134a Freon right on the can.

After further investigation you are right but I will still consider my self a laymen.
