Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, only on the trailer or the truck isnt working either, you checked the trailer supply fuses as well as the regular fuses?
Ok long as you have power coming in from the trailer plug on the truck the issue would have to be with the trailer wiring or the lights on the trailer, Inspect for power and ground to the inoperative lights. If the bulbs are blown, replace the bulbs, if the sockets have corrosion the sockets would need to be replace.d The main ground should be good for the trailer with the other side lights working. Inspect all splice points or scotch locks for the left side and wiggle the harness to see if its a wiring issue.
That would be what to check with a voltmeter to see if there is a voltage drop or short in the plug.
here is the schematic for your trailer circuit
