    2006 legacy 2.5 SOHC. AC won’t work. I’ve recovered/vacuumed/ and charge to .90lbs. Fuses /relays checked and good to go. TX valve replaced- high pressure switch replaced. AC compressor not engaging. Not getting power to compressor at plug? What am I missing. I used a paper clip at relay plug in to force power to the compressor and system blows cold but won’t stay on when the relay is put back in. I read somewhere that when companies started using an ECM with the system it got more complicated. What’s happening? I work for a GM dealership and the coworkers who have 30+years of experience with all AC don’t have an answer.
