Power running boards

2015 Yukon Denali power board stays out. When I shut door it tries to go in but only about 1/2” then goes back out. Acts like it thinks door is open.

Very likely you have a hinge assembly binding and the motor is hitting its torque limit. This can be caused by dirt and grit building up in the pivot points.

I sprayed silicone wd 40 on all moving parts. Can I disassemble them and clean them?

If you “help” it by closing the door and lifting with your foot can you make it close?

I’ve used my hands and it will not budge any farther

Might have a hinge bound up due to mis-alignment. Might try and loosen the mounting bolts on them a little and see if that helps.

I checked everything and after lubing it up, and I guess sitting a while it will let me push it up in , then it forces itself back out

OK now that everything is lubed up I can push it in with my hands and it’ll stay in but when I open the door it opens back up when I shut the door. It won’t go back in like it’s hung up but I can help it with my hands every time and was trying to keep doing it to see if it would eventually work correctly. Do you think it could be a motor?

Yeah-these retractable running boards can be a pain. The motor controller has a torque limit setting and if it sees more than that, it just says “F-it, I’m not gonna do anything.”

It’s for this reason I have given up trying to get them working on our 2013. Iowa winter roads just mess them all up. If I find a decent set of fixed running boards, I’m swapping them out.
