Anyone with an 05/06 experience airflow in footwell vents when footwell is not selected? I get some airflow in the footwell regardless of the setting. I am tempted to just block off the footwell vents for now.
Did some more investigating into this with mityvac and an Amazon endoscope camera. I don't seem to have a vacuum leak. Testing each actuator revealed that they all hold vacuum. Test at the actuators, at the back of the dash switch, under the hood where the vacuum hose feeds into the firewall and at the intake manifold. All checks out and holds vacuum.
Endoscope camera shows the blend door for the dash vents and footwell opening and closing as it should. I do notice some twisting of the door when it's closing. It doesn't seem the door closes as tight as it should. I didn't see anything blocking but I need to do some investigating. Electronic temp blend door is working as it should as well. Can feel and hear it moving
This is proving a bit frustrating.
