Does your truck have a pushrod that actuates the b rake switch at the pedal?

Check it to make sure the retaining clip is not loose or missing. Also check to see if the electrical connectrions have not come loose and that the switch is getting actuated with th epedal being pressed.

Let me know if that helps.

Here is a schematic of the exterior lights.

Check the Orange wire at brake switch, on top of brake pedal for battery voltage. If voltage is available, use a jumper wire to bridge the Orange and White wire. If brake lights come on, the switch is bad or out of adjustment.

Do you mean only the trailer stop lights are not working?
Are the brake lights on vehicle body working correctly?

The CHMSL fuse (10A) is for the brake lights. If battery voltage is not available athe trailer connector, check the CHMSL fuse. Use a test lamp to test both ends of the fuse. If voltage is available and none found at trailer connector (Light Blue wire), you have an open circuit between the fuse and trailer connector.
