Ok so I do not know much about AC but whenever I start my truck the AC blows good then stops then starts again. it will do this for about 1 minute or so then works good after that. Also to give you a little history on this issue. about 6 months or more ago when I started the truck it would do the same thing it does now but there was this grinding sound that would go when the AC would stop, it sounded like plastic gears grinding together. It does not make the grinding sound anymore but still starts and stops for a minute or so. Also I believe that when I change the direction from the face vents to the floor vents it does not change to the floor vent. Anyways any help would be very much appreciated. Thanks for reading my long boring post

Blend door. I've noticed even my 14 is a little odd sometimes. I think it defaults to the floor because I'll start the truck with the AC on and I can feel it blowing on my feet at first, and I have to swing the direction knob out and back to get it up to the top vents.

Since you had a grinding noise your blend door motor may be gone.
