Thinking of ditching the Mirage. Other options, or, maybe some tech advice?

I have zero problems with my car windshield fogging up in winter, and I never use a/c in the winter. Even with my bum heater core, I didn't have THAT big of a deal with fogging.

Do you warm your car up? Does that help?

I'm thinking you may have a problem like a leak somewhere that is raising interior humidity somehow. Nobody else has had this issue, even our guy up in Thunder Bay.
