Air Conditioning problem
2005 Hyundai Atos 4 cyl Front Wheel Drive Manual 80000 miles
The a/c works fine around town, but on a trip over 50 miles, it quits blowing cold air. After it sits a couple of hours, it cools again. Does it need coolant or is there a filter somewhere that needs to be cleaned? The part in front of the radiator is clean.
