Need more hand-holding, please. Been reading old posts but it's not sinking in, I guess.
Got air and heat but it
only blows out the floor vent. It'd be nice to have defrost, etc.! I know the plastic door pull is broken but the cable doesn't have any movement anyway. I mean - moving the selector switch does nothing. I don't hear any actuators actuatin' - no clicking under the dash. Is this most likely a vac problem? Any other thoughts?
