Subaru Forester's AC is intermittent ( blows cold air until around 30 minutes of driving, cycles daily) How do I fix this?
Asked by Kevoneh Jun 11, 2018 at 01:44 PM about the 2016 Subaru Forester 2.5i Premium
Question type: Maintenance & Repair
Subaru is 2 years old. The AC works fine for the first 30 minutes of driving, then
starts blowing hot air. After that, the car blows hot air for the rest of the day or
until I stop for an hour or so. I have already stopped at the Subaru service but
the AC stopped again 2 days after.

If compressor clutch is clicking on and off the system is low on freon clutch should stay engaged all the time.
You did not say what the Subaru shop did. If they charged the system and it stopped working 2 days later you have a leak which must be repaired before charging it again.

Having same problem with '16 OB. Let me know what you find. I've ruled out compressor and both dash-mounted sensors.
My 15 Forester has lots of problems with the AC from the get go. Finally Subaru replaced the compressor, hoses, evaporator and all the seals. Now it seems to work correctly. Had to listen to a lot of BS from the local dealer in the mean time.

Yes, but what was actually defective? Couldn't have been all those parts....
Leaks, lots of them but I did not examine all the parts. They tried (and failed) to fix it by replacing all the O rings. It is possible that defective parts did not allow a proper seal.

My 2015 Subaru Forester has so many issues in the last 2 weeks. Of course I am at 105,000 just passed the 100,000 warranty. 3 days ago: The AC is intermittent. As someone mentioned above. Blows cold for 30 mins then turns warm. Yesterday: Radio would not turn off . Today: Radio display is whacked out. Strange mix of patterns and jumbles, no words, no symbols. Just mixed up.
