Description: In this pt.2 I am reinstalling the blend door with a 2 pc. door from heatertreater. Which involves making some cuts through the plastic behind the glove box, and through the air box for access to the blend door. I did have a problem with the door not passing the auto centering test after the install. So when u hook up the battery or check codes with a scan tool the door cycles back and fourth, for verification of its function. If the door has any obstructions it will fail the test and freeze open. The codes have to be cleared, or unhook battery for a minute to clear it. Then diagnose the problem, repair and return to service. My doors problem was that it was stopping at the heater core portion to soon, so I had to bend the door in a vice away from the heater core to give the door more travel. That is working just fine, at least the last 8 x`s I activated the self test. And the door had a solid seal around the heater core opening, even after the adjustment.
