Factory A/C System Woes

[Rick Bollinger]

If your making water then things are working. No water should be leaking by your heat valve. Blend door needs to seal completely If it's original it is most likely not and can almost guarantee if you haven't taken the evap coil plenum apart to clean dirt and junk is keeping it from sealing as well. Then there is the fresh air door. This is in the cowl behind the vacuum diaphragm on the passenger side. Same deal it should be closed when all controls are to the left. If it does not seal it will pull warm air from the outside as well. Then the door inside the cab. It will be open circulating the cool air back through the evap coil cooling the air more all the time. When I installed all new doors in my system I did have to trim up the rubber a little bit here and there because it would bind up. But my old stuff was dry and brittle and did not seal at all. Plus had a lot of small leaves and dirt in it as well.
