I have a 2021 Forte GT where the windshield continuously builds up condensation on the outside while the A/C is on. The problem is most noticeable at night or early mornings and I cant drive w/o having the wipers on all night long. The problem appears related to air coming out of the center dash near the vents where the windshield meets the dashboard. It looks like air is only supposed to come out when defrost is on. The dealership was puzzled if this normal or something that needs to be serviced under warranty. The service dept. is not open at night when I can demonstrate the problem. They said they cant help since they cant verify the fogging up issue. Covering the vent with a piece of paper temporarily resolve the problem. Is this normal? What should I do about this?
