85 Heater issues
Hey does anyone have an exploded view of the HVAC system and/or a vacumm diagram of it? Truck won't select from vents, to floor, or defrost, took the glove box out and found two linkages, one is to hot/cold and the other just seems to select vents or floor, but doesn't seem to change to defrost either way I push it, took the dash apart and see that the select switch has a bunch of vacumm lines running to it, one line runs down to a vacumm servo it looks like and the others run behind the heater box, haven't taken the heater box out yet, little to much white stuff on the ground and no shop sucks. Thanks
