While driving in heavy rain a/c button started flashing and all windows fogged up. I took it to the dealership 3-31-07, they performed diagnosis and replaced a/c magnetic clutch relay. Next heavy rain on April 14, 2007, the ac/button started flashing and all windows fogged up. I took the car to the dealership and they found the clutch assembly shorting when wet. Replaced clutch assembly. In August, during a heavy rain, the a/c button started flashing and all windows fogged up. I took the car to the dealership and they said the a/c belt was not tight. They tighten the a/c belt and said if it happened again, the belt would have to be replaced. Today, October 15, 2007, the same thing happened. I haven't taken it to the dealership because I don't think they can fix the problem.
