Yes, It has to be done by weight. Now you need to take it to a vehicle AC place, have the refrigerant sucked out of it onto a recovery machine that also creates a vacuum and the correct amount of gas added by weight. They use subtractive scales to weigh the gas cylinder. It also has to be the right type of gas.

Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).
The fix: Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process. In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.
If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.
the air mix door may be stuck or broke does it blow cold air on hot days after the freon is replaced and for how long it may be leaking back out ?? it may be an door acutator as well or linkage
i need to know how is not cooling the car?
is the fan blowing air or is the blowing air not cold?
it probably isnt cold.lets try that.
put a set of 134a ac gauges on the system and verify pressures.if it has low freon you may hear the compressor turning on and off.if so for sure its low and you will just need to add freon.
go get a 134a fron fill kit not the conversion kit.
and begin to fill untill the comp stays on and air is blowing cold.then stop filling and enjoy.
do not over fill as this will cause it to not cool again.
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.
