Problem Heater/AC - Air flow
I am a Newbi with a problem on a 1999 F250 PSD. All of the airflow is coming out of the defrost vents in both heat and air condition. I have researched some of the old threads on this problem and agree that I have a vacuum leak which I am trying to track down. I have removed the vacuum line at the pump and place my finger on the hole resulting in the pump stop working so I believe the pump is good. I then unhooked the lines that go inside the dash and the line going to the front 4x4 hubs plus the line to the solenoid hope that the pump would shut off. No Luck. I now believe that I have a bad vacuum canister or are there other line that I missed?? Any help would be appreciated.
