I have a 2005 outback and my ac quit working. I took it to the dealer and they told me it had a hole in the condenser, which they said was a common problem. The said it was easy for a rock or screw to go through the slats in the front grill and hit the tubing. I have owned my cars and never heard of this happening. Has any heard of this problem. Also any suggestions on how not to have this happen in the future.:
