I was in a hit and run a week ago, guy ended up hitting my side mirror sending it flying into my cab, it shattered my window and a lot of glass entered my defrost vents, after the window was replaced, I switched my vents to floor to blow the glass out. Thinking it was gone I switched to dash vents, now I can not direct air between the floor, dash, or defrost, its just stuck on the four on the dash. Can anyone direct me how to go about removing the dash to remove any glass, and if anyone could post the location of the damper that switches between the vents if be most greatful.
