Be sure fluid level is proper. IF the ebrake is stuck on ever so slightly that will cause this problem as well. Theres a small chance that the sending unit in the brake master cylinder is bad. The sole purpose of this is to check fluid level. If the brake fluid resevoir is full, a quick test would be to (with key off) unplug the sending unit into the master cylinder and then start vehicle. This would let you know rather or not this is the issue. Let me know if you need any farther assitance, thank you for using fixya.com

Hey Paul, it's most likely a wiring problem. There is one wire designated for just the running lights. What type of plug does the truck have? Probably 6 or 7 way (6 or 7 wire). You can check the plug-in at the truck with a multi-meter to see if there's power at that point. If there is, then the problem is somewhere from the trailer plug to the lights on the trailer. If you have a 7 way plug, the center plug is for aux. power (back up lights on what you pull, if equipped). One wire is power to the camper battery for a breakaway switch, one for left turn and stop, one for right turn and stop, a ground wire, one for running lights, and one for trailer brakes. To determine what wire does what, 1st with meter check volts of all wires w/ truck and trailer hooked up, truck running, power wire to battery for breakaway should show voltage if equipped w/ a trickle charge, brake wire will show low voltage, approx. 2 volts, apply brakes and should go up to approx. 12 volts, put on L turn signal, meter should go up and down, as power to blinker pulses on and off, do the same to determine which is the R turn signal (put foot on truck brakes will show voltage to brake lights AND brakes, continue w/ process of elimination to determine which is running lights, and exactly where power is not going.

Probably one or more (fuse(s) ) under hood in power distribution box.

Hello.
We would suggest that you look at the wiring connector under the bed, that feeds the taillamps.
You will probably find a coroded wire in the connector. If the 3rd brake lamp works, all of the fuses and switches are good.
Testimonial: "All connectors were fine. It ended up being that both brake light blubs blew at the same time. Thanks"
