Ok so I just recently traded my truck for a 96 HX. it has some random problems and found some fixes on here already. one thing I cant find is I am having problems with the buttons that switch what vents the air goes through. When I hit the button for the windshield to defog it it blows it out at my feet. and the one for the floor goes thru the dash vents towards you. one of them works correctly and none of them blow onto the windshield. makes it kinda hard to see when it fogs up. has anyone had this problem before? any ideas on how to fix it or what I should check? thanks
