The AC in my 87 944 started to not work one day while the car was idling, but would work fine when the car was driving (higher RPMs). This continued and got worse, until one day the AC stopped working all together. So it seemed to me that the compressor went bad.

I just installed a new compressor (and oil), and a new drier.

I also found the slow leak it had, someone pinched an o-ring on the top of the compressor, and now it has no leaks.

Everything was going good until installing the refrigerant.

Only a little went into the system (way too little).

And here is what I have now.

Low side static 80psi
High side static 80psi

Low side running 80psi (AC clutch IS engaged)
High side running 80psi

The compressor was replaced with a brand new unit and the clutch IS engaged.

I'm not totally new to AC systems but I'm no expert at all.

From what I read it seems like the expansion valve is stuck open, since I'm getting NO pressure differences when the car is running and clutch is engaged. All it's doing is just rotating the refrigerant through the system.

Does this seems right? I want to make sure before taking the system apart again and buying a new expansion valve.

Thanks
