Ok guys, one of the running boards (curb side) on the wife's Explorer (2010 Limited) will not deploy when you open the door. I switched from "auto" to "always down" to always retracted and back to "auto" with no change.
Any clue? I got under neath for a look and could see no evidence of any road damage. also looks like a pretty tight unit to gain access to circuits.
appreciate any thoughts before I take it to dealer.
