Alright, I'll try to make this short and to the point. Basically in 48 hours lost all refrigerant and blowing ambient warm air.
Replaced both high/low pressure lines with seals, dryer, condenser and pressure switches during engine swap July/20. slowly lost refrigerant by November when I noticed compressor clutch cycling on/off more than normal.
This last weekend checked static pressure and was equivalent to ambient temp (~70F). Refilled system with refrigerant and A/C coolant die from Autozone. Got cold air and clutch cycles at more appropriate intervals.
Looked around with A/C leak check blue light and glasses and only noticed old splotches on the dryer from possibly when connecting refrigerant bottle to low end. Cleaned it all up checked again after 20 minute A/C operation during idle run. Didn't notice any escaped dye.
Today (four days later), tried to run A/C, got hot ambient air. Outside Air Temp was around 75F. compressor clutch kicks on for less than a second then disengages during cycles on and off. Seems to not hold and run the compressor for more than a split second. Searched all over except possibly behind the dash where the blower is for any A/C refrigerant and dye escaping.
Only thing I can imagine is either there is a leak somewhere in the dash where the evaporator is and I can't see it or maybe one of the pressure switches is failing (doubtful as it just worked after refilling the system) or the compressor, but also doubtful as it worked fine after filling the system. If I can't find a leak anywhere in the engine bay, how can I check the evaporator behind the dash? Thanks!
