How to repair vent selector./ Hemitexas
I had the same problem on my Dodge Ram this summer. I could hear it blowing hard but air was comming out vents very poorly. I had called a few places and they all gave me a bunch of "BS"on how they had to pull the dash! So I removed the 3 screws which holds the fan blower, after removing the blower, I reached up threw the housing and the diverter/door which when open lets air in from outsde,and when closed resurculates inside air, this door had broke off the peg it was attached to and had simply fell down onto the top of blower causing the airflow restriction! I had pulled outnthe glove box to get as good of view as possible, I carefully pulled door out from bottum where I removed blower, I then put 3M 100% silicone on the side which stops outside air from entering,I then carefully put this door back up into its closed position and after about 20 mins it was cured. I then put blower and glove box back in and problem is fixed! Now air blows as hard as it should.
