When the A/C started acting up, the front windshield would suddenly fog up instantly. This would only happen on occasion, like in the rain. I have been fortunate that it has happened when I can pull over, and I can limit the issue by driving with my windows cracked. Because the A/C issue hasn't been resolved, the defogger is still a problem.

This fall, my heater has also stopped. Now the defogger doesn't work at all. Taking it in to get it looked at again. This car has had more issues...sigh
