I have a 2010 Georgetown Forest River, Ford V10 Chassi. I cannot figure this out. The driver side turn signal (oblong amber) and parking light was not working. Bulb is good. Camper neighbor next to me suggested that the maybe the lower marker light that also works as the turn signal. (round amber one) might have the turn signal bulb burned out. Changed that bulb, but turn signal still does not work.. but now the parking light on both the oblong and round amber works but still no turn signal. Hope this makes sense. Has anyone out there have any suggestions? Trying to figure out why turn signal does not work. (flasher on that side does not work either) Thank you for any helpful suggestions..
Does the brakelight work on that side? If not it is likely in the feed somewhere. Either fuse/relay in the TV, in the trailer wiring connector, or if they are all good, perhaps painfully in the trailer wiring.
