My 2013 (185,000 miles) is blowing cold-ish, but not cold air and the compressor is running continuously... R134a is correctly filled, but the high pressure runs normal and the low pressure is a bit low. I think it's the compressor control valve, and they're sold online for $50 or so. I've replaced similar components before and I know how to evacuate the system, but I'm having a hard time locating where it goes, and how it goes in. Is there room to get to it? Has anyone replaced theirs?

 

These videos should help you. You'll need a pair of retaining ring pliers to remove and to install the retaining ring that holds the solenoid valve in the cavity of the compressor.

 

@bclexus Thanks!
