The air is blowing hard and cold, it's just coming from all vents defrost facial vents and floor all at once regardless of what position you have the dial. And the rear air controls blow just fine just warm air. What would be my fix?

Good morning,

This sounds like you have a vacuum leak to the motors inside the truck. They used vacuum motors to control mode doors and electric for the blend doors.

I attached a picture for the rear blend door for you.

Remove the left rear quarter cover inside the truck and it is right there.

Look under the hood for any broken or loose vacuum lines on the passenger side where the line comes through the firewall.
