Lights in bed wont come on

[ramblin man]

MY 2017 1500 Laramie LED lights in bed are not working. I removed the passenger side light and bench tested it works fine. The lights on back of cab are also working. Could not find information on what fuse is powering that light . Anybody had a problem similar to this? Every thing on electrical system is factory stock.

Check the wire harness behind the left front wheel well liner. The harness tends to rub and chaf on the left front cab mount.
