AC / Electrical situation:
I replaced my battery yesterday and After doing so, my air conditioner no longer blows cold air. I have confirmed that the compressor and Clutch are both engaged whennever I turn on my AC. Clutch kicks on as soon as I press my AC button and stays on until I turn off the AC button.
Air cycles appropriately through proper vents (floor, windshield, etc). Heat works fine.
Condenser coil is not getting cold…no water dripping.
New battery has fewer CCAs then previous battery, which is shot to hell and was leaking sulphuric smell throughout the car.

Forgot to mention…I had them test the refrigerant level and they said it was on the lower end of the acceptable range (lower end of green). AC worked perfectly prior to changing battery.


Check both refrigerant lines at the firewall and make sure that they are equally cold after 5 or 10 minutes of the compressor being engaged. If they are you will more than likely need to recalibrate the actuators or possibly replace a defective actuator.  If they are not cold or equally cold then there is a refrigerant problem.
