Troubleshooting Seven Blade Vehicle Side Trailer Hook Up with Constant Power to Right Turn Signal
Question:
Thank you for your reply. The blade seems fine and there is zero corrosion. Besides the seven pin/blade connector, my truck Also has a four pin connector which has the same symptoms. I checked all the fuses and I now wonder if it is possible if there is a faulty module. I don’t even know if there is a controlling module.

Your right turn signal and brake blade are right next to the 12V power on your 7-way. It is not uncommon at all for corrosion or debris to cause a connection between these blades that would cause exactly what you are describing of a constant power on that blade.
I recommend using some sand paper and an old toothbrush to really clean those blades and then use some dielectric grease # 11755 to keep the moisture, corrosion, and debris from happening in the future. If cleaning your blades does not solve the problem, then disconnect the trailer connector and test the US Car Connection directly behind it for functions using your circuit tester like # PTW2993. If that is good, then replace the trailer connector with a compatible connector like # 74682.
