About a week ago I noticed my ac wasn't working very good.

What is your question?

Last week I noticed my air didn't seem to be working as it usually does. Then the other night I noticed my windows were very fogged over when they shouldn't have been. Today I noticed why they were foggy, the ac is blowing on the windshield. The setting are set to blow out the front facing vents. Also at one point the air wouldn't blow at all. Then just can back on a while later. It has a new fan that was put in this past summer (June sometime).
