No park lights rear only
no parking lights @ rear tails, yes ! do you have a wire diagram, get one, there in the back of the haynes repair manuel. could be a bad connection @ rear, a wire may be shorted, corroded, after all, these wires are subject to road salt, debris, etc., inspect them closely, turn your parking lights on, pull on the wire harness, wiggle it, see if lights come on. have a helper watch for you when you do this. do your brake lights work? make sure your tails are in good shape, these light components corrode inside, so inspect them closely, then, follow the wire harness from rear to front along frame rail, to check condition of wires, all of them, if in good condition, check under dash, where you replaced switch, check fuses, use your wire diagram to locate and under stand the color of wires that come from the rear, and there function, remember, we are dealing with the tails, what powers them, and which ones do what. ignor all other wires, keep it simple dude. have a trouble light with you, It looks like an ice pick, with a wire lead on it and a aligator clip on it to attach to a good ground. electrical problems have a bad ground, remember that. by now you should know your wires for the tails, usually there green. with your taillights on, and your trouble light hooked up, check each wire to see if the troublelight goes on, this wire is good, if troublelight does not light up, wire has no continuity, therefore its bad. patience is a virtue, remember that. test wires on a circuit you know works, so you can feel more positive about what your doing, these problems can be easy, they can be @#$!%& , remeber, your trying to power up your tails, keep it simple, one wire @ a time. good luck,
