Hi All,
I recently bought a trailer that will hold two ATV's, but I'm having problems with the lights. When the trailer is connected to my GMC Sierra 6 pin connector, the right trailer light blinks and does everything its suppose too, but the left trailer light doesn't blink or does light up when brake is pressed, (but it does light up when you turn the lights on), except when pressing brakes and blinker, "like I mentioned above."
I checked all my truck's fuses and their all okay. I checked my truck's lights and they all work fine. The trailer lights all work fine, because I had them connected to a tester box and both lights
blinked on this tester box, so it has to be my truck that has the problem. Any Solutions?
