rear lights

[RBatson]

I have a 2005 B Touring Cruiser. The rear parking lights, runnings lights and licence plate light will not light. I have checked the switch and all the fuses I can find. The front light work correctly.

Does anyone have any ideas to correct this problem

Probably one of the fuses for the "trailer lights" circuit. GS usually wired the rear lights from Ford's trailer prep circuit. These are located in the fuse box under the hood.

Make sure your trailer wiring plug/harness isnt damaged and shorting out.

Thanks , I checked the ford fuses first thing, and the toad lights are working. And the ground is good.

Check the ground screw where it goes into the frame in the back. I found a problem there. It looks like everything was good, but the screw that was holding the ground was intermittently losing contact. Just wiggle this to see if it is bad. I put one of those star washers there , the kind that bites into the metal as you tighten it.

We found the problem. There was a corroded Connector over the rear axle.
It looks like where Gulf Stream connected to the Ford wiring. We cleaned it up and put dialectic grease on connections.

Thanks for everyones suggestions.
