No cold air from Air conditioner
AC not providing any cold air. Compressor will engage (and stay engaged) when I jumper out low pressure switch, but still no cold air. I reconnected pressure switch and charged system and am reading about 47 psi on low pressure side without AC turned on. When I turn on AC now, compressor engages but quickly disengages after about 1.5 to 2 secs - the disengagement corresponds with low pressure side dropping to about 26 psi (appears low pressure switch is kicking it off which Mazda book says occurs at 22-28 psi). After clutch disengages, low pressure side builds back up and when it reaches about 43 psi (takes about 4-5 secs) the compressor clutch briefly re-engages (Mazda book says clutch re-engages at 40-47 psi). And then the whole cycle continually repeats. Do you think I have line blockage at perhaps orifice tube that may be restricting flow? Also next day, low side pressure will be quite a bit lower (with AC turned off)……thinking I may also have a refrigerant leak…..Any other ideas or recommendations? thank you
