My right brake light and blinker work on the truck. somewhere between the taillight and trailer hook-up (both 7pin and flat4) the right blinker and brake light stop working on the trailer. I know its the truck cause when I hook up the trailer to my dads truck, the lights on the trailer work fine.

One, what causes this? Two how do I fix it?

anyone got a wiring schematic for this part of the truck?

under the hood, power distribution center, 15 amp fuse.

Been down this road a lot, and that is what seems to go bad. Found it caused in the past by a bad wire on the flat 4 connector.

Should be fuse #47

Thanks! sure enough fuse #47 was blown, I had looked in the fuse box before and found the "trailer lights" 30 amp fuse was not blown, but i didn't realize that each rear light had its own fuse, thanks again.
