Hello, I'm Danny.

All of the output drivers are controlled by the ECM. It sound like this is what your having trouble with. If you want to send me the VIN number vehicle-identification-number from your truck I can find what ECM it came equipped with to help you find a replacement. I've attached a picture below of the ECM location on your truck. Hope this helps and thanks for using 2CarPros.
