1988 Jeep Cherokee, brake lights work, headlights work, turn signals/hazzards work...TAIL lights dont work, nor does the light for the lic plate or the dashboard light. We have replaced all the fuses and bulbs but when hooked to a volt meter, the tail light socket is showing no power. Tail light socket is new.
Is there a way to jerry-rig a wire directly to tail lights, so that it can manually be turned on?

If you have any extra fuses, try replacing the ones for the head lights and tail lights. Make sure the fuses you replace are the same color as the ones you replace them with, that way the voltages are the same. Another issue is that a flasher could be going out.
if you have side marker lights then you have a short between them and the tail light sockets, its the same circuit , you need a meter to check this, remove one tail light bulb,, put the black lead to the base of the bulb holder, and the red lead to the little dab of solder inside the bulb socket, if your show 12v ,, then its the bulb , if not,, the socket isn't getting power and you need to back track the short or broken wire, ( make sure that the lights are on when doing this test ) normally the problem will be found where the wires in the harness come into the trunk area, or its just a bad ground,, so check that first
That does not make any sense. Do the tail lights work? There are supposed to be separate filaments for brake lights, tail lights, and turn signals. In particular the center brake light should not be possible to be confused with tail lights or signals. Does it come on? If not, then you probably have no brake lights at all, and that is probably because of the bad fuse or the switch on the brake pedal for the brake lights. If there is some sort of cross over between tail light and brake lights, that is usually from a bad light socket ground; which results in current backing up from one system to another. But then each is usually only half brightness.
The problem is that the tail lights, light bulbs get too hot and melt the plastic where the bulb socket goes into the lens assembly. On the lens assembly you will see one to three metal tabs where the socket fits into. Lift up the tab a little bit with a screw driver and place a small amount of either metal or plastic underneath the tab so it will get a good connection. It will fix the problem.
The problem is what they call the printed circuit in the tail light. Remove the twist off light bulb connector. You will see the contacts inside and that the plastic is warped. You can purchase the entire fixture for about $350 if you replace it yourself. A dealer will charge about $450 per tail light fixture. Chrysler won't admit they have a problem that they should have issued a recall for. The problem is that if your stoplights are out, you may be involved in a rear end collision. Chrysler doesn't care. What I did was purchase a right angle tailight bulb holder and standard #1197 stoplight bulbs from advance auto supply. You have to trim the existing socket a little and splice the wires for the new light socket, but it beats paying $900 for replacing the two fixtures. I fixed mine about a year ago and haven't had any problems.
sounds like the directional switch maybe bad (lever on steering column ) if u open the column u can test the wires and see if it is passing current to tail lights have seen these go bad many times in older jeeps
