I know we are still in the cold months but I've been experiencing a problem lately where the inside of my vehicle is humid. No I don't have water standing anywhere or anything like that. All of my windows are up sometimes it's really cold outside sometimes it's not. When I get my vehicle I'll notice that the windshield is wet. It hasn't rained or anything like that. And the inside also smells like it's musty like it's wet but it's not. Any idea what could cause something like this?
