Park/Running Lights come on with brakes

[Cajun83]

Fuses 14-16 and 8 has no power with test light. Everything works as normal except front amber comes on when braking…

if you have some Electrical Contact Cleaner spray

Give a squirt or two into the trailer plugs at the rear bumper
just a bit of corrosion in those plugs , can do strange things because all of your lights are in those recepticles
