Hey Jeff, since all of your trailer taillight functions aren't working that would indicate that you probably have a ground issue. To fix this try cleaning off all of the pins of the trailer wiring as just a bit of corrosion causes this problem almost every time.

Hey Jeff, did cleaning the trailer wiring pins clear up the lighting issue on your Titan? Your update could make it easier for others troubleshooting the same problem.

@JamesonC it did actually help the problem out there's was a lot of dirt and corrosion on the pins ?? in the 7 way I also found a fuse in the fuse block under the hood for the trailer lights it was the one behind underneath the cowl
