I have a 2003 Chrysler PT Cruiser Tour 4 cyl . When the temperature reached 90 and the humidity was 100% last night, my car AC quit working, even put out warm, moist air. After it sat a while, it seemed to be working again. Could it have "iced over" like a home AC unit can?
Could it have Iced Over? Most definitely! I have seen this occur under similar conditions. This can also occur when the Freon level is slightly lower than normal. But I the weather conditions are not normally at 100% humidity, I wouldn't worry about it.
