Its a JX.... I borrowed my friends recovery machine and I evacuated it and there was only like 300 grams in the system that holds 800 grams. The system does not hold a vacuum so there is a leak somewhere. A small one. So my issue could be 2 fold. Bad expansion valve along with a small leak somewher...

Its a JX.... I borrowed my friends recovery machine and I evacuated it and there was only like 300 grams in the system that holds 800 grams. The system does not hold a vacuum so there is a leak somewhere. A small one. But anyway, I tried to fill it back up, and when I got to about 500 grams, the com...

Expansion Valve? Anybody want to give their thoughts? Vacuum on low end? Virtually no change on high side?

Dug more into it, and at 1800 RPM, the low side goes really low to 5psi and stays there forever. The high side goes from 150 to about 155 or so and stays there. The compressor still runs constantly. At idle and static, the pressures are still the same as I mentioned before. I'm thinking expansion va...

Make sure your temp doors are working- go to full heat and full cold see if there is a differential. At 35 psi lo side- you should have cold return lines to compressor and cooling inside evap. Yes, I failed to mention this. The air is a lot hotter when I have it at full heat. When I have it on cool...

The A/C blows warm and its the same temp as the outside air. The A/C clutch does engage and stays engaged. The low line DOES NOT get cold, but the hi...
