I have 1997 f250 light duty and I'm having a problem with my tail lights. I have turn signals, brake lights, hazards but not any tail lights. Is this just a fuse or something in the wiring? I don't have my owners manual so I don't know which fuse it would be if this is the case. Any help would be greatly, greatly appreciated. Thanks in advance!

 

I'm having a similar problem on my 01 F150. Everything on the truck works correctly but when I hookup to either of two trailers-no taillights. Driving me crazy. The wiring diagram from the Haynes manual shows the stop, park/turn, side marker, both left and right receiving power from the main light switch which receives power from the power distribution box fuse 7, 15A.
In troubleshooting mine I have power down to the connector that goes to the trailer connector. Nothing beyond. Got to figure out what the connector number is or something.
All lights on both trailers worked previously and nothing dramatic has happened so I'm at a loss. Maybe I'll just spray it with electronic contact cleaner with my fingers crossed.

 

I am having a similar problem. I put a new light switch in and a new parking light, dash light relay and still no tail lights. The fuse is good.

 

Are you talking about the reverse lights (white lights) or just the rear lights dont come on when the lights are turned on? Because I had the reverse lights stop coming on if that what you mean. Let me know.
