Ok here is my problem .. my dash is all torn apart and I cant get my air to blow through the vents.. which I dont care about... but I cant get it to go from cold to hot either like that knob isnt working b/c the linkage is still ... is there just a way to delete all of the knobs and vaccuum lines seeing as I dont have a/c anymore anyways and just open all the vents for heat and hook the fan up to a seperate switch??? I know there has to be a way any help would rock .. thanks
