My tail lights on the driver side only do not work I have a 2007 Dodge Ram 1500.The lights on the passenger side work fine

The wiring of the harness is parallel to the sides. hence you will need to trace the driverr side lamp connection backwards to the joining section of the line. Please check on the ground connection of the lamp assembly, remove and clean and reset after confirming that the groundis fine but the voltage does not reach on switch on of the park lamps. If this becomes difficult to trace just take a parallel wires from the passenger side lamp to be connected to the non working side. this will work fine. Please take care to insulate.Good day
