Electrical problem
1999 Lincoln Town Car V8 Two Wheel Drive Automatic 200k miles

Have Headlights, have brakelights, however no tail lights or markers? Checked every fuse under dash. Check fuses and relays under hood. Looked for a fusible link under driver side door threshold. Looked for a trouble code with an OBD scanner, found nothing?

When the switch is disconnected from the wiring harness I should have all lights controlled by the switch on. Headlights are on, Lights On Bell is ringing no tail lights? I've tried auto position as well as every other position.I've switched the light switch with a known working switch, same make & model. Apparently, the switch is not the issue?

Please advise-Thanks

HEADLIGHT SWITCH Disconnect headlight switch harness connector. Continuity should be as specified between terminals with switch in specified position. See HEADLIGHT SWITCH TEST table. See Fig. 2 . If continuity is not as specified, replace headlight switch.

There is a handful of fuses that need to be checked, also there is a lighting module that can be out as well.

Trace the wires shown in the diagram use an ohm meter, it should read below 5 ohms, if it reads high or OL, it is shorted to ground, this should blow the fuse for the tail lights. Have you checked that?

Or a wire may have corrodes inside the plastic, and this will not blow the fuse. Don't forget to check the ground!

Here are some wiring diagrams for you.

Please let us know happens so it will help others.

Best, Ken

The rear brake lights wont work. The middle brake light works. The Fuse is good and the lamps are good. There is no voltage going to the brake lights when the peddle is pressed.

Turn signals work ok? The lower brake lites are wired through the multifunction switch. The lower brake lites and turn use the same bulb filament, just not at the same time. If you need a wiring diagram holler?
