Does anyone else have issues with the AC where it seems to just run the fan for a bit instead of full AC? I have noticed that if AC is set to on and I have the fan speed at 2 or 3 with temp at 70 I get cold air for awhile, but, at times it feels like just outside air running and I notice a smell inside and feels immediately humid. Then, shortly after, I feel the cold AC air again. I changed the setting to Auto, but, I still notice it. Is this normal behavior? I also noticed this happens more when braking or sitting at a red light.
