Ok I have an 82 monte with the ac ripped out. No vacuum canister in the engine bay. Two lines are missing I believe from under the dash coming from the heater control and two that are cut. The purple I have going to my carb and grey to the heat valve just before the heater core. No idea what to do. Only have heat on the floor and at max ac. Very little when sitting still and more but not a lot when moving please help winter is almost here.
