We have a 2012 Expedition. We are original owners, just yesterday the passenger side running boards failed. Ive tried the lubrication route but with no success. The motor runs but it sounds like a walrus wailing. Ive tried to turn the shaft to see if i could manually move but to no avail. Yesterday i the board could be ‘lifted’ up to close and it would move out easily. But now it doesnt move at all and i cannot manually close. Anyone have any ideas before i yank it off tge vehicle. Really dint want to pay 1200 for the motor.
