Tri-way power board on sierra Denali ultimate failing

[Laxaustin]

I have the tri-way running boards on the 2017 Sierra that fail to extend on the drivers side. This problem was brought to my dealer 10 months ago and they put a “bandaid”on it to make it last till my truck was out of warranty, (they replaced the hinge brackets instead of the failing motor). I believe the motor has been the issue all along in that the steps will extend down most of the time however they need assistance to extend to the tire, and they are incredibly slow to extend to the normal position. After getting the vehicle back from the dealership the boards work with the door, they work with the button in the truck but the kick step button on the actual board is out of sync or something.  When I hit the driver side kick button it extends immediately  out to the tire and skips over the door, the passenger side kick step won’t extend the board at all. Does anyone have any insight to what the dealership may have messed up that would cause this issue with the kick steps. I brought it back to the dealer and they told me to basically pound dirt and nothing they did when repairing the driver side brackets would cause problems with the passenger side. Any help would be appreciated.

Welcome to the site.

 

Was the repair work done under warranty?

Have you thought about going to another dealership? You are not married just to one, take it somewhere else.

I do plan on taking it to another dealership but hate going there without being knowledgeable about what is happening, I was hoping for some insight into why they would be out of sync with just the kick button and nothing else. Also the dealership wants to charge me 2200 for repair, I believe it’s just a motor that I found for 320$. The boards are OEM gm part so I don’t understand why there is virtually no information on these boards out there.

I’m going through a similar situation with my 2017 Sierra Denali as well, except on the passenger side. I was about to make a new post, but since this is so current I thought I would add it here and save the “search button comments” .

 

My passenger side running board is noticeably slower than the drivers side. The kick switch never worked ( I bought the truck used ) and it was something I can live without. Lately the passenger side running board extends and slowly retracts back before the door is closed. I searched the forums and found that a member removed the kick switch, removed the wires, put di-electric grease on the connections, taped it up, put it back together and it was good to go. I tried that, but try as I may I could not remove the wires from the connector as the red tab on the connector ( the member said slide it ) would not budge. I tried prying it, but didn’t want to put so much force as to break it. I silicone sprayed all the arms bushings,  did a fuse pull reset and all seemed well until I drove it this morning. Now as soon as I open the passenger side the door extends all the way to the tire. When I close the door it closes, but now it seems to open and close at will while I’m driving. I ended up pulling the fuse.

 

 

Does anyone have any idea what I could have done to cause this, or any remedies? I can go without the steps but my 4’11 girlfriend cannot. Would my kick switch have anything to do with this? Also, what if I bypassed the kick switch as in cut off the connections temporarily until I get a new kick switch? Will my boards still operate? My understanding is the kick switch is basically a jumper off the motor for the running boards and is activated when you kick them.

 

Any help would be appreciated. It is of warranty, and the closest dealer is quite the distance away and I’d rather fix it myself is possible.
