Trailering Electrical

Just wondering if anyone else has run in to something similar for a problem. When I pull a trailer, the right side indicator/brake light does not come on. The left side does. Hummer lights all work. A tester at the trailer plug shows the same, nothing on the right. I go to the fuse box on the drivers side dash, the fuse for the left trailer has power to both sides of the fuse and the fuse for the right has nothing. No power either side. From there, without schematics, I do not know where it would go. But my thinking tells me it could be a relay? But where?

Ok..so if anyone has this problem, or related to flashers/indicators/brakes on the truck acting up...there is a 10 pin relay/module located on the back of the fuse box on the drivers dash. You have to take apart several dash panels to get to it.



It's about $120 part# 10383321 and they call it a flasher module.
