I have a 2014 Chevy Cruze... just 6 months old. I am getting huge amounts of condensation on my outside windshield, just above the air vents. The opening in those dash vents blow air-conditioned cold air onto the windshield. The only way I can control it is to keep a folded up bath towel laying on top of the vents. Any other kind of towel isn't thick enough. I've been to my Chevy dealer. He said they ran some diagnostic tests that did not come up with any errors. The condensation is HUGE, and it's happening when it's humid. I've never had a car that does this. There doesn't seem to be any control whatsoever with those dash/windshield vents. No matter what direction I set the vents to (feet, upper combo of both), the same amount of air whooshes up through those vents. It's a nightmare... I already spoke to someone at Chevy Customer Care. They're the ones who set me up with today's appointment. Any suggestions?
