i checked all fuses and they're all fine,
can you guys help with the location of the brake fuse and brake relay if any,
i notice two days ago that the right side turned on very weak and latter it was fine i attache a trailer i just bought, i went around the block to test the new trailer brakes i just installed and when i came back i had no brake lights track or trailer, but i still have turn signals and emergency lights, I checked the brake pedal switch and i found power coming out when i depress the pedal but nothing goes to the brake lights

Did you have the recall done on the cruise control deactivation switch? if it has shorted out it will cause you to have no brake lights.

 

I had the same issue a couple of weeks ago. The brake lights were out, but the third light on the cab was working. Turn signals worked fine, but the hazards were erratic. I could not locate a fuse at all, nor does the factory service manual indicate a location. I removed the turn signal switch from the column, and ran the point to point circuit test on it, but found nothing wrong. I put it back in, plugged the harness back in, then everything worked again normally, and has ever since.

 

Had my brake light switch replaced. Problem solved
