i have 86 190e 2.3-16. i father just had the whole a/c system replaced basically. (compressor, dryer, pushbutton, all hoses) now it seems that hot air comes from the center vents as cold air comes from the side vents or vice versa. it feels like both hot and cold air are trying to come out of the center vent at once? anyone with info please help!
