2014 Yukon Denali running boards stopped working

Asked by Madmolly Dec 22, 2016 at 07:03 AM about the 2014 GMC Yukon Denali

Question type: Maintenance & Repair

How can I get the running boards to work. Already
checked the fuse and it was fine. What's the next
step? Both quit at the same time so I wouldn't think
it's a motor.

Look in the owner's manual to see if you can find a relay for the running boards. If it has a relay it just might be bad.

I know this is an Old Post. But for anybody else who has encountered this issue, check your alternator I had a faulty alternator the battery was not holding a charge which causes the running boards to go into storage mode. 30 minutes later and a new alternator, I performed the procedure to initiate the running boards and they started right up. If both of your running boards fail at the same time it's unlikely to be a mechanical issue. Steps should be one check the fuse 2 try the initiation sequence you can find that just by Googling it and then three check the power that's going to those running boards in this scenario mine was an alternator issue and the battery was never fully charged enough to run the boards. Hope this helps
