There was a recall on this, take to the dealer and they will replace the whole socket on this.

Check & clean connector underneath at rear, usually just forward of front bumper, up near frame, drivers side. Does this have a trailer towing plug on it by chance?

Hello.
This sounds like you have a bad ground on your Dakota. Trace the wires back until you see that one of the wires is connected to the body or frame with a small screw or small bolt. Make sure that your have a good clean ground to work with.
Another thing that you can check for is to see if there is another light out somewhere else on the truck. Its like christmas lights, when one bulb goes, it can effect all the others just as well. The only other option is to check your fuses, get the fuse diagram and see what controls the taillights. On my truck I have the wrong fuse in there cause only the taillights to work and not the brake lights. Vehicles are very picky with there fuses. If the correct fuse is in there, make sure that the fuse isnt burnt out. You can check that by seeing if the filament in there looks burn or is broken like it popped. Hope this helps!

Hello. The symptoms you are describing are likely due to a poor ground. Temporarily install a new ground wire by securing a piece of copper wire to the frame with a self tapping screw. Use this ground wire along with the hot wire to see if each of these lights works. If it does, trace the ground wire back to the frame, unscrew it and clean up the metal with emery cloth so you reestablish a good ground.
