2000 toyota tundra trailer lights not working. If I place hazards on while lights are on only right side flashes and whole dash lights flash too. 2005 Toyota Tundra. Asked by JamesDean in Poway CA on July 03 2010.

Toyota tundra parkingtail lights not workingnot a fuse under hood or relay. You would have to trace the harness under the dash down the kick panel and under the hood. I replaced the flasher relay and it still does not work.

2004 Toyota Tundra V8-47L. Then test the wires coming out of the converter. Hazards work only when lights are off.

Use a circuit tester like 40376 if needed to test the wires going into the converter box from the truck. All of the running lights and one of the turn lights were no longer working. Frichco228 Jul 11 2020.

I plugged the trailer back in but no lights. That has always been the issue for me if I had one part of the lights not work when other trailer lights like the brakes did work. Toyotas response is the Tundra does not feature a center differential which would become a weak point in the drivetrain.
