#32 of 59 2006 Subaru Forester air conditioner problem
Jul 05, 2011 (5:39 am)
My air conditioner works well for a while, blowing very cold air. The, suddenly the compressor seems to shut off and only warm air is emitted. This seems to happen especially on hot days, and especially if I am headed downhill (i.e. when my engine is revving down). If I accelerate, raising RPMs, the compressor seems to kick back in. I can do this 5 or 6 times. Eventually, even that fails. Then I have to turn off the system and let it rest. About 10 minutes later I can restart the air conditioner, and it cools perfectly. I have 100,000 plus miles. I recently started using a phone charger in my cigarette lighter and recently had the head gasket changed. Could either of these two changes be responsible? A post I saw on this site mentioned something about an air conditioner clutch and another post mentioned a coolant temperature sensor. Does anyone have an opinion about my problem?

When my air conditioner started acting like that, I had to have the computer module for the a/c replaced. Not cheap but after that the a/c worked fine.
I'm still having problems with the car overheating when I run the a/c. I can turn it on but if I travel on the interstate when I get off, it starts to overheat. I've replaced the head gasket so I didn't expect this to happen again. Any ideas?
#34 of 59 2009 Forester AC problem
Jul 25, 2011 (6:34 am)
The AC on my 2009 Forester (58,000 miles) quit working. The compressor makes a lot of noise (rattles) when the AC is turned on. I took it to the dealer and was told I had a clog in the system. They said the rattle was due to the compressor pulling vacuum on the low side and that pressure on the high side was over 200 lbs. I was told there was no way to find the clog and the only sure way to fix it was to replace all components in the system. Total cost around $3,000.
I would like to know if there are any other options.

I had another problem with my a/c this summer. When I would drive on the interstate with the a/c on and then get off, the car would overheat. I just had the head gasket replaced 18 months ago so I didn't think it was that again. I took it to an awesome mechanic and discovered the connection to the second fan was not working properly. He fixed that at minimal cost and now it works perfectly.

This does not sound right. In 5 decades of car ownership I have not heard of a "clog" in the AC system. Also, being unable to find the problem, and needing to replace the whole system, and the cost of $3,000, all sound wrong. It is well worth seeking a second opinion from another dealer or a good independent shop.

I can imagine debris causing a clog, but the price sure does sound high.
Funny thing is they usually leak...

Over the years on various cars we have had such problems as a plugged evaporator drain, intermittent cooling, minor refrigerant leaks, an untended leak where loss of refrigerant and its lubricating properties ruined the compressor, and a couple of failed compressor clutches. But no clogs.

I had a leaky compressor on a '91 Ford Escort GT.
I was mad because the A/C was a $460 option, but fixing it cost $700 at the time. And I had just serviced the A/C the year before.
The shop gave me a break and didn't charge me for the freon the 2nd time.

Hello, my Forester is doing the exact same thing and dealer recommends head gasket replacement. Can you tell me exactly what second fan connection was not working properly on your car? What is the "second fan" and where is it located? Thanks very much - you might save me a ton of money!

The second fan is located on the passenger side of the car at the very front right behind the headlight. Good luck
