    I am not near my fuse note right now but a common problem is that the small wires going from the tow switch to BCM break due to vibration or fatigue especially if the tilt wheel feature is used a lot.

    It's not hard to fix, just a pain. I want to say it's a 24 gauge blue and red pair joined like speaker wire but I don't quite recall.
