Hey guys,
I am a new member, and I joined to receive a little help. My 2007 Avalanche LTZ is having power running board issues. When I close the door, the running board folds up, but then immediately unfolds to the door open position. Then when I pick up enough speed, it folds up again, until I stop, and it unfolds. The passenger side is working fine. They are factory installed.


I would appreciate any help.
