Is it possible that the compressor is overheating? Maybe too much friction in the bearings for the pulley? This is just a shot in the dark, really. How long does it take for the system to "reset?"

Thanks for your reply.
It can vary greatly. It does seem to take longer in direct sunlight so that overheating is a possibility. But then, what is the solution?
I have found that it will cut in and out by itself and under some conditions, leaving the system in partial or full recirculate mode will allow the interior to stay cool. But in strong sunlight, this is not adequate.

Well, again, hard to say, but if it is a friction problem then perhaps spraying the bearings with lithium grease will help. The compressor pulley is clutch activated, so try not to get any grease on the pressure surface or the plates may slip.
Again, just a shot in the dark. If the system is not low on refrigerant and the compressor works (when it works!), there must be something telling it to disengage so often. I am not sure what the triggers are, but often they have fail safe systems (shutting down if overheating would be considered a fail safe).

Check to make sure that there is water draining below the car during operation. If it isn't dumping a significant puddle at idle, then chances are the condensor is freezing over and that will cause it to spew warm air.
Tinted windows help a lot.
My 05 LGT Wagon has been excellent during the past week of high 80s low 90s here in NYC with very high humidity.
#10 of 59 Proper ac compressor oil for 03' Forester
Jan 16, 2009 (8:07 pm)
I'm changing my ac compressor and it calls for a 200 oil, the auto parts shop have 100 or 150, what is the difference and is the 200 necessary?
#11 of 59 Subaru Forester Air Conditioning Overheating
Apr 27, 2009 (1:49 pm)
My 98 Forester overheats when I am travelling and have the air conditioning on. It doesn't overheat when I'm travelling around town only when I am travelling on the highway for at least 30 minutes. This past time I was 60 miles from home. I had travelled approximately 30 minutes. I slowed down in traffic and the heat gauge shot up but not in the red area. I quickly shut the a/c off and turned on the heat which cooled everything down so I could make it home.
This happened last year and I replaced the thermostat. Anyone have any idea what could cause this? Thank you,

When my Miata started acting up, I changed the water pump first, then the T-stat. The latter is what fixed it, though.
Running the heat simply helps dissipate heat from the engine bay, but it's only a short-term fix to get you home.

Did you ever figure out what was wrong? I'm having this exact same issue now with my '04 Forester. Was it the thermostat by any chance?
