Hello, my name is***** you for the question. Can you tell me if all of the electronics on the truck are stock including the radio?

Thank you. There are several common issues on this truck. Most of the time it is either the blinker arm assembly that is shorting internally, or there is a short in the rear junction block. I would locate this block right near the rear bumper. Unplug each connector and make sure that they are clean and tight. If they are then you will need a voltage meter to run some tests to find the issue. If you need to proceed this way let me know and I can assist you with some tests.

It is 3:00 am. I will try what you said about the box tomorrow if it is not raining and get back to you.
