I purchased a 2003 F150 Supercrew Lariat about 3 years ago. It never would blow air down on the floor and I just lived with it. I got rather cold when it was -20C but so be it. Recently it just started another issue. When I have the AC on vent and accelerate it changes the air flow from the vents to the defrosrt mode. This is probably two separate issues so if you can help it would be appreciated. I will be keeping the truck for a few more years so I guess I should fix both issues. It has the electronic climate controls.
