Just to be clear here, the compressor is working now?
What I would do is if possible tap the area of the valve with a small hammer and see if it changes anything. I am looking for info on the expansion valve for you, but try the tapping and see if the pressures change at all. I have in the past broken them free with a little tapping. I agree this is the likely problem as long as the new compressor is good. If the pressure isn't getting high then it's quite possible the new compressor isn't pushing the freon.
Please give me a few to see what I can come up with for the expansion valve for you.
I'm sorry, 2 different manuals, one the factory manual and nothing in there on the expansion valve replacement.
It is buried in there and sadly, at least on my last experience with this, I had no luck sneaking it out the front by removing the bolt. A lot had to come out to move it enough to get it out. The hole in the firewall isn't large enough to get it out of the front.
Curious about your pressure, what is it with the engine off? Perhaps the pressure you are reading is just the freon itself and the new compressor isn't doing it's job. I would say if the pressure is close to that 110 psi with nothing on, you might have a bad compressor. If that's the case try that before going after that H valve.
Sounds good. Might save a whole lot of hassle!
Yeah, it looks it to me. You have equal pressures and the compressor hasn't even been turned on. This is probably just the pressure from the gas in there and the ambient air temp. My money is on a bad compressor. Typically even if it had a bad H valve, it would at least show some pressure difference hi to low and certainly a ton of pressure on the high side if it can't get through there. I do think you have a compressor issue and would replace it again before taking the dash apart here.
