99 Ram Tail Light Problem

I have a 99 Ram and have no tail lights. Blinkers work, Front light markers work, Fuses are good in both fuse boxes, but tail lights do not. Any help would be great!

Does your guage dash lights work okay? It's definitely and open circuit between your headlight switch and the taillight bulbs. Try checking under the bed of your pickup, if it has ever been in an accident and any removal of the taillight housings, they may not have been replaced correctly or the ground wire from the taillight housings may have become disconnected. Also, check to see with an ohm meter to see if there is any current at all at the taillight sockets with the parking lights turned on. Hope this helps?

When mine quit it had to do with the trailer wiring.

Still perplexed on this problem. Today removed trailer wiring - a harness with 4 plugs to put in line with current. Hit hazard lights - bottom lights blinked. Hit brakes - top lights came on. Put in reverse - bottom light socket came on. Turned on main lights - nothing???? Any help to this subject would be greatly appreciated. - fuses all good and dash lights and dome lights also come on!
