Power running board problem

[Steved460]

I have a 2021 Yukon. The power running boards seem to be receiving signals to lower and then close when the door is 1st opened. I have lubricated them so that is not the problem. I am thinking maybe the door open/close switch. Where is the switch on this truck? If I open the door and the running board lowers and then closes, I can open the door the 2nd time and it work fine.
If anyone has any other ideas, I am game to hear them.
Thanks

I have not seen that one on our 2022 Yukon but it does not sound good. You could get hurt. Call a Dealer and tell them it's a safety hazard.

helps to drive into the car wash and thoroughly rinse the threshold motor assembly, while extending the thresholds and then dripping lubricant for bicycle chains into the joints

If it dosnt work the first time, but works right after that, its not a lubrication issue. Sounds like more of an electronic/programing issue to me.
