Defrost failed

[DieselHamster]

I drove my truck in yesterday to get winter tires installed. On the way I could not get any air at all on the front windshield. I was driving with it partially fogged over. I could hear the fan battling away, but it was like the vents were not directing the air flow to the windscreen.

Picking up the truck with new tires, then back at a Ford dealership to look at the defrost issue.
