I have an '08 XC90 3.2L and the A/C isn't cycling. Low

Customer Question

Hi, I have an '08 XC90 3.2L and the A/C isn't cycling. Low pressure needle jogs between 54-55 lbs. Seems like a linear pressure problem, but I don't have repair information for this newer system. Any help?

most the time you will need than proportion h valve replaced and ac compressor the variable valve on compressor can go bad and cause it also . h valve or proportion valve must inspected for clogged from failed ac dryer it will have lot small balls if is clean than replace compressor

Enes, You said "proportion" valve. Are you referring to the expansion valve on firewall? I will check system for failed drier and report back to you.
