So that CRV I got yesterday also did not have working AC. I was hoping it was low on R134. So I got a can from the autoparts store with the built in gauge. Hooked it up and started filling the system (I know it was not completely empty as I tapped the low side shrader valve and got some pressure). Well the pressure jumped like it usually does when I opened the fill valve, and the compressor kicked on as you would expect. However the pressure never dropped, and by te time I turned the can off it had spiked the gauge. So I dug my real gauge set from the garage. Hooked it up and am showing 85 on the low side and about 110 on the high side with the compressor running. I’m thinking bad expansion valve. What are your guys thoughts??
Also if I rev the motor the air will get cool not cold but noticeably cooler. As soon as it goes back to idle it’s warm again.
