My air conditioning is weak. Very weak. It's been converted to modern freon and for years I never used it. Then about 3 years ago I tried charging it and it started working. It has worked for 3 years until this season. I attached the cylinder and it doesn't take any more refrigerant. The gauge on the can says green and the pipe to the evaporator in the engine compartment is cold. But inside the car the air blows just a little cooler than ambient.

Does this sound like a problem with the vent baffles? Using the inside air button makes little difference.

The condenser fan starts as it should and the compressor runs constantly at idle in the driveway.

The compressor cycles under way as it has always did.

Is there something I can do before I try to find a competent 240 air conditioning person in the Philly area?

Thanks
