Hey guys: I'm reasonably competent on AC systems, but this one has me stumped.
03 Explorer with 4L V6. AC was blowing ice cold, but then car sat for 2 weeks while I worked on something else, now does not blow cold at all. Emptied the system, pulled a vacuum and refilled with 24oz R134a (capacity is 34oz, so I'm a little light I know): still not even a hint of cold air. Nothing.
Compressor engages and cycles normally.
My gauges should be showing ~30psi low side and ~150psi high side, based on ambient temp and humidity. Instead, with the compressor engaged I see 60psi low side and 150psi high side. When the compressor disengages, high side pressure slowly drops while low side pressure never moves; neither up nor down.
I could understand a clog not allowing refrigerant to travel from low side to high, but if that's the case how would the high side have gotten anything in it at all?
Thoughts?
