1997 F150
The front lights work, but NO Tail Lights Work,
No brake lights, No running Lights, NO Lights working in the Rear
The Turn Signal Indicators on the dash board Blink Rapidly
I replaced the Fuel Tank Fill Hose, after putting the bed back on
No tail lights work now
I checked the Fuses under the dashboard, checked the bulbs, checked the
connection I unplugged to remove the bed
Nothing looks wrong
Can anyone give me some Good Advice where to check next to fix this

 

Ok Found the Problem
There is a connection point above the spare tire
You can only reach it by lowering the spare
There was a connection unplugged
Must have come undone when the Truck bed was removed

 

Glad you found it! Thanks for the update with the solution. I think you had everyone buffaloed on that one.

 

I have Bad Arthritis so it was very hard to get under the truck,
I decided to trace the wire harness to see where I cut into it,
That's when I dropped the spare to see the wires and there it was.
A broken connection, If I had just disconnected the rear lights there,
I would not have to remove the rear lights, Live and Learn
