I've vacuumed out the Low AC port, then put more refrigerant in, but compressor doesn't seem to turn on anymore. There is a small black dryer/canister with the sight glass on the right side of the car, and a switch with purple wires on top of it. Connectors look good, pulling them off, I measured a short between the two contacts of the switch. There is another switch directly underneath the High AC port with green wires, this measures open, but the brown wires that plug into that connector measures shorted. Is this correct for the Rossion (at rest, not running). I took pictures but don't know how to post on here. Thanks everybody!
