When I have the selector set to floor heat, the air comes out at the
windshield exhaust as if I had the defroster selected. The 4 dashboard vents
do work when they are selected, but I can never get discharge to the floor.
Does anyone know where the dashpot is located that directs the air from
floor to windshield?
hi Al....is it possible the vaccum is the same for the heater and the
4wd?? I have a 99blazer 4x4..my ex-mechanic left a batch of wires
against the manifold and they burned..he didnt repair it..my 4wd went
out..4x4 indicator lights (no click either) are dead..also my heat/ac
blower is acting like this guys..today I rewired all the burnt
wires...they are beside the front passenger wheel ...but no luck....any

I have no idea where they pull the vacuum for the four wheel drive. In our
(Tucson) public library they have vacuum diagrams for almost all American
cars. Check yours out. Be sure to check the reference section. You can make
copies of the pages you need.
I found the dashpot that routes the air to the floor. The shaft it operates
is broken inside the vent assembly. I have no idea how I'm going to get this
thing out of the car. Looks like the entire dash would have to come out
first. I guess I'm going to have cold feet all winter. Next time, I'll try a
foreign SUV instead of the crap Detroit is pushing on us.
