Could someone tell me where the turn signal module is located. I am trying to troubleshoot an electrical issue with rear rt tail lamp. The light stays lite even when the light switch is off and glows bright with no turn signal or brake light…looks like the brake and turn signal lamps are illuminated at the same time. They come on as soon as you turn the key on. I switched the connections on the other tail light and it follows. I trace the wires straight from the rear wiring harness to the PCB module so it looks as if the turn signal module may be internal to the PCB?
