Re: lil bit of a defroster problem
There is a door inside your heater box just under your glove box that deflects the air different ways when you change it on your heater control, the clip that holds the rod to the door to open and close it brakes therefor the air flow will not change. Just fixed mine in my 83.

Re: lil bit of a defroster problem
the air valve to change from def to floor is over your gas pedal,behind glove box is a bulging part to the air box, removing the outside will give access to the clip, ontop check that the cables havn't bent or the plastic cracked(where the screw goes threw to ajust and fasten). i posted a pic a bit ago of mine when i fixed my 85......i'll post again when i get home from work later
