Why are the lights not working on my Nissan Titan XD?
If the truck receptacle shows ok, the problem is with the trailer plug or further back with the trailer wiring/bulbs.

A short would blow a fuse. The number 1 terminal (white wire) of your 7 pin plug should be your ground, your hitch should not be your ground.

Begin by cleaning the ground connections. Each component should have its own ground to the frame of the trailer. If the trailer lights flicker on and off, there is a good chance the trailer is grounding by way of the hitch instead of through the trailer’s wiring connector.
There should be an indicator for each individual function. If the tester responds to each individual system, the trailer wiring system is probably the cause of the problem. If one or several test results do not provide a response from the tester, the tow vehicle itself might be the problem.

How do you repair a left turn light?
Begin at the trailer connector on the trailer. Examine it for corrosion or damage and clean or repair if needed. Trace the wire for the left turn circuit (usually a yellow wire) from the connector back to the left turn signal lamp. Look for pinched wires and loose connections. At the lamp, check for a rusty bulb socket.
