So i have a 17’ KW T680 developed this issue today where the right front turn signal bulb stays on with the parking lights. When i turn the parking lights off all the lights are off but now when i put the right turn signal all lights flash minus the clearance lamps. This only happens with the right turn signal. When the parking lamps are on all the lights don’t flash but the front turn signal bulb in the headlight stays steady while fender signal flashes and trailer signal flashes no problem. Does anyone have any idea what could be going on.?

Right turn signal and park light circuits are probably shorted together somewhere.
DCJFreight and BoxCarKidd Thank this. -
Unplug the harness to that light while still connected to a trailer. Does everything else still work?

I will try this. Will let you know the outcome tomorrow.

Your wiring is definatly shorted together somewhere. Probably to far from the light. If you have continuity between those 2 circuits there shorted together.
