Re: Defroster?

And in addition to the elbows (labeled DEF in picture) there is a cable operated swing arm or lever on the right side (VALVE) which moves the defroster/heater flap inside the plenum. Check to see when you are in heater it is all the way one direction and when the lever is moved to defrost, the lever moves all the way the other direction. It is about a 1 1/2" or so swing
While not very likely, one other thing to check. If the elbows and valve seem OK, how much gap is there between the chrome molding at rear of dash and windshield. If that has somehow been mounted too close or the pad has stretched and covered things, the air is very restricted. You should be able to stand outside and look inside at the bottom of windshield-back of dash area and see a nice gap and the air slots.
