| So I did jump those two big wires and I’m happy to say that the compressor works and it’s blowing ac at 54 degrees!!!! It still needs 1 1/2 cans more of redtek and a new trinary switch (hopefully that is the fix). So a huuuuuuuuggggeeee relief and a huuuuge weight lifted off my chest. I did notice that the Rpms did drop. Is this normal for a ej22 engine? |

| Did I cut the connection? Yes. Was it my fault? Yes it was, but without mistakes and failures we cannot learn. I do see your post Dave. Could this post have been prevented? Maybe. With your help I needed a new ac thermostat and a new trinary switch and my confidence in the Vanagon ac system has greatly increased. I always try to look at a positive outlook in a negative situation. The ac still needs work though. New trinary switch needs to be installed, about can and a half of redtek needs to be in the system and the van drops Rpms with the ac on. I still have to work on these issues. I want to thank everyone and this community for helping me out. |

Yep, life is a learning experience.
The WBX had provision to raise engine speed when A/C is on. The wire to the compressor clutch tee'd and went to the Idle control relay.
I'm sure Subaru has an idle speed bump system too.
How to marry those two platforms or if it can even be done ? I don't know.
All engines slow with A/C turned on.
As an average trinary switches close for the clutch with about 30 psi in the system.

| Nice! I assume I’ll lose a little bit of refrigerant but I’ll be charging it anyway. |

Ok so I installed a Vintage air trinary switch and it works!! Finally. The compressor turned right on and I bought new connectors for the trinary switch and the vw ac wiring. See below. I also added two more cans of redtek refrigerant. Now the vans ac is working but not blowing that cold. When I charged the system the ambient temperature was about 80 degrees out. It has been humid out in so cal and after 2 can of redtek added, I took it for a test drive and it was blowing maybe 60-64 degrees. I took a pic so you can see my hi and low pressure. I checked for leaks but not see any. My system was brand new so maybe it takes more then 3 1/2 cans of redtek? Let me know what you guys think.

At what RPM were those pressures taken? At a 50+ pound suction pressure your average evap coil temp is 61F. Your high side pressure is low too. At 3.5 cans in I would not add more refrigerant. You had better results with less. Take pressure readings at 2000 RPM and post the results.
Were both valves on your gauge manifold closed when you read pressures? |

A new expansion valve was installed. Here is the part number. 253260109
The sensor bulb was already installed on the valve and it was facing up or towards to roof of the van. I wrapped the expansion valve in tar tape.
I then began to search for leaks or anything that I might have missed/overlooked and then I found that there is a kink in the condenser line. I believe this might be the issue, but I am not sure.

Dave,
Here is a picture of the expansion valve with the sensor bulb. Do you think the link in the condenser would add to the issue of no cold air as well?

| Ahh I see. Did you see the kink in my condenser high line? Do you think that could add to the issue of not enough pressure for the high side? |

Yes, the kink in the condenser pipe is a big problem. It acts just like an orifice tube and it appears to be located on the vapour side of the condenser flow (ie, before the vapour gets to the condenser to be cooled and condense into liquid).
That kink needs to be repaired. Where is your high-side service port located? Specifically, is it located on the line before the condenser or the line after the condenser? I suspect that in any event, your high-side service port is located after the kink and for that reason will not accurately reflect the high-side pressure due to the restriction. This might explain why your low-side pressures are in the 50psi range. You want somewhere in the range of 27 to 32 psi, once the system has stabilized. You then adjust the refrigerant fill (adding or releasing refrigerant) to achieve the lowest stable vent temperature.
With a fill producing 50 psi on the low side, quite apart from the kink in your condenser line, your refrigerant fill is likely an overfill. Just to get a better idea before taking the system apart for the kink repair, you can release some refrigerant until the low-side pressure is around 28 to 30 psi and then check your vent temps and high side pressure. There will still be poor performance because the temperature delta at the condenser will not be high enough to maximize efficiency.

| Update. I installed a new ac condenser and charged the system. My pressures on the low side are 40 psi and the high side is 175-200 psi. Still no cold air. Here is what I noticed. The ac compressor is not cycling. It is always staying on. Which makes me believe the expansion valve (djkeev thought it was bad) is bad. The expansion valve could not be opening/ closing which could lead to these issues. What do you guys think? I agree with DJkeev that the aftermarket expansion Valves are not good. |

| I found a new expansion valve from my auto parts store. I’ll install it and re charge it and go from there. |
