If you have a trailer plug that plugs into the factory harness, remove it, see if that does the trick.

I don't have one but there looks like there's a ground connected to it and it's screwed to the metal underneath my truck n it looks all rusty


When you installed the new switch did you make sure it was secured correctly and all wires were plugged in and nothing was loose? Those switches have adjust-ability of the lever on the side
