Strange, never heard of this issue. Any fault codes when you scan it?

Scan the truck, but the dealer will work and ultimately you will most likely need the dealers IDS to diagnose the issue. But being a 2015 I'd bet you are out of warranty for this type of repair.

of course

I can replace the unit myself if its bad --- I think but probably has to be programmed to truck?

I think you would be ok since it is already enabled to operate in the PCM. I think your could just swap it out.

Thanks for your help. I unplugged, tightened the connections, shook out a tad of water , cleaned all connections , tested all lines , and when plugged back in all worked fine. We had a TON of rain here , perhaps just an anomaly . Ill keep an eye on it
