I own a 2007 sunset trail. Now the left backlight will not light when braking or flashing. I've check wiring in the connection box and it all looks fine. Are there any fuse in the electrical path? I swapped bulbs also to make sure.
If you have the factory towing package in your truck chect the fuses in the power center under the hood. Ther is a fuse for each side of the traile a charging fuse and a trailer light fuse

Check your tow vehicle. Most modern vehicls have a seperate fure fore trailer signals. Lso you didntsay if the running lites (parking) are working on the same side. If not then you could be missing the ground side. (-)
