While in drive the reverse lights are still on & stay on most the time. Also every time I make a right turn, my brights come on when I hit the right blinker on.

Hello,

This sounds like a BCM problem which tries these systems together. Here is the location of the unit and how the reverse lights are wired so you can see how they work. I would try a used one and plug it in, you may need to get it programmed to the truck it should cost about $120.00.

Check out the diagrams (below). Please let us know what happens.

Cheers, Ken
