2004 Subaru Outback

 

Question: AC blows hot after driving 10 minutes

Question

I have a 2004 Subaru Outback LL Bean H6 3.0. The AC works great idling in the parking lot, but after driving for about 10 minutes it starts blowing warm air. If it sits overnight it works again until I drive it. Any ideas?

    There can be a few issues that will cause this, A/C Compressor clutch, pressure switch or another electrical issue. I suggest having a Subaru shop look at this to determine what is wrong. You can look here to get an idea of what a diagnosis for this will run you: http://repairpal.com/estimator?car_type_id=4112

    Did you ever had your car fixed? What was the problem? I also have an Outback, LL Bean with the same problem and I would like to get more info before expending more on parts and fixes that doesn't fix the problem.

    Thanks,

    Yes, finally. Subaru has a service bulletin 10-74-02 for an updated AC compressor revolution sensor which turned out to be the problem.
