I have a 2014 Toyota Corolla that I bought new, still under manufacturer warranty. For several months, in all kinds of weather, the inside of the front windshield fogs up and stays that way no matter what I try. I've run the defroster, drive with windows down, cleaned the inside of the windshield, and replaced the cabin air filter.
The other day, in dry 75 degree weather I drove it on a two hour trip and couldn't keep the windshield from fogging up no matter what I did with the climate control system--ran the A/C, turned the A/C off, drove with windows down, ran the defroster, and nothing seemed to do the trick. It's not enough to be a safety hazard, but it is an annoyance. It seems to be worse on the bottom third of the windshield.
As an aside, I have a 2009 Camry and I don't have this problem at all. I can drive the Camry in the same weather and it operates normally. I know how to defrost a windshield in cold/wet weather that causes normal brief fogging, so that's not the issue. I live in central Texas, FWIW.
Is it possible that a bad heater core is the source of the problem? Or something else, such as a bad seal? Any thoughts on how I approach the service writer at the dealership on this?
Thanks in advance for the help.
