Before I start, I'll say I know this issue has been discussed ad nausium, but I'd to get opinions on WHY our defrost is not nearly as effective as other vehicles.
I'll preface this by saying I HAVE checked my recirculating door and it is working as designed. When the door is set to outside air, it pulls outside air.
The other day it was raining and around 48 degrees. I had been volunteering in the rain all day, and was not soaked, but damp. As I was driving home, I had the heat on my feet and I noticed the windshield starting to fog. So I just changed the HVAC to defrost. There was little fogging so I left the fan speed on 2 (4 speed fan) thinking that should be enough. Shortly the fog was not disappearing, in fact, it was getting worse. I checked to make sure the air was on outside air and turned the fan up to 3. The fog kept getting worse. At this point, ONLY 80% of the windshield was clear, the side windows were completely fogged so you could not see out of them. (The rear window defroster works perfectly). I cranked the fan up to 4 and it clears a small section on the driver and passenger window; just enough to see out of. It stayed like that for the rest of my drive with the fan speed on full. I then got out of the car and it sat idling with the defrost kicking for 15 minutes. When I got back in the windows were almost clear, but quickly began fogging up again. They are almost impossible to keep clear when it is ranting and chilly. This happens even when j am dry.
Does anyone have any idea why the Cruze defrost system is so bad?? Is my car doing what it's supposed to? It seems everyone has this problem, so I'd assume it's working as designed. But why is it designed to not work? My girlfriend has a Buick Verano and with the climate set on auto the windows stay completely clear no matter how much moisture is inside or how hot the interior is. The Verano is about the same size as the Cruze...in other cars when I turn defrost on it clears all fog within seconds even on low fan speeds. Any ideas why the Cruze can't do that? It was above the temp cutoff for the compressor...so it should've been drying the air. I even hit the A/C button to turn it on (I know it's on with defrost) and it didn't make a difference.
Interested to hear ideas or other experiences. It's worth noting that I never had the inside frost issue where my windows frosted up on the inside in the winter. But it is kind of annoying to have to drive down the road with the fan blasting air any time it rains. Would changing my cabin air filter help? I should be doing that soon anyways.
