I have a 2008 Elantra and the switch for the windshield defrost quit working. It started making a noise when I would switch from the head to the feet or to the defrost and then it just stays on the head now and only that. I turn the dial to the other areas and it just stays on the head. Anyone know of a way to fix this? My brother is a parts manager at a Ford dealer and is pretty sure it is a faulty climate control switch which is a dealer only item that goes for 629.00. I live in Canada so it would be nice to have the heat on the windshield as well. Thank you.
