2008 Forester Auto n/a. A/c compressor doesn't come on, in cool or defronst mode. The switch light is on.
The a/c compressor doesn't switch on. Static pressure is about 30lbs, and the pressure seems to cycle correctly when the relay is bypassed, down to (about 20?).
Pull the relay and cross the power directly, it works.
Swap the relay with one of the headlight relays, still nothing.
The pressure switch connector has 4 wires. I tried crossing every combination. Apparently one combination blew the fuse under the dash panel.
Nothing switched on the compressor.
Any thoughts other than low freon?
