A/C Compressor sometimes does not turn on
Just had the system completely vacuumed and refilled - When the compressor turns on, it works great. But about 1/4 times, it just will not engage until about 15-20 minutes later. I can't figure it out. Does anyone have any ideas why the compressor would wait to turn on, if the pressure checks out fine?
Thanks, Geoff |

Re: A/C Compressor sometimes does not turn on
I'd try pulling codes from the climate control unit; it's ridiculously easy. See the attached (toward the end).

Re: A/C Compressor sometimes does not turn on
Looks like it's reading a Code 15 - Refrigerant temp sensor open
Is this something I can take care of, or should I take it to the Subie dealership? |

See page 22 for the location of that sensor. Probably not the easiest thing to get to, but you could get lucky and it just be a loose plug or something.

Re: A/C Compressor sometimes does not turn on
So I have to remove the glove box, and it's somewhere down there? My guess is that the system would need to be evac'd beforehand?

Re: A/C Compressor sometimes does not turn on
I'm not exactly sure how to change that sensor out. I'd first get a replacement sensor and then evac the system, then take apart as much of the dash/glovebox area and swap it out. Test it before putting it back together.
