I have this same problem. Just so I understand, Why would a charge effect having cold air on pass vents, but not drivers? I would think the system would have the same temperature out of both sides with a low charge. Is there something electronic that makes this happen? If any one knows I would be very grateful Thanks!
Makes perfect sense. Thank you very much. After taking the lower dash apart and seeing everything function smoothly, I believe I will give a small charge a try.Do you know what the low pressure should be roughly @ 100 degrees out side standing still? I believe the high side should be roughly double the out temp. I will also cool the condenser with a hose to check the pressure drops. Thank you very much!!
