It is possible that there is a blown fuse or relay related to the tow package wiring that is causing the problem. Use the vehicle owner's manual to find the locations.
It is also possible that there is a break in the wire somewhere. You will need to use a circuit tester like # PTW2993 if needed to test the wire as you work your way forward on the truck.
If the right side stop light also does not work, it could be a blown stop light or CHMSL fuse. If the turn signal function works on that same circuit (a 7-Way has combined brake and turn signals at the 3:00 and 9:00 positions) then it could be a dirty or corroded trailer connector.
