Question about 2001 Lincoln Town Car
It seems to happen with the main light switch in "Auto" during the day, but I'm leaving it in "Off " now to check this theory. When it goes the interior lights don't work and head and tail lights are on all the time until the ignition switch is turned off.
The first place to start would be to have the LCM checked for DTC'S - diagnostic trouble code , rather then guessing .
B1689 Autolamp Delay Input Circuit Failure LCM GO to Pinpoint Test F . B1691 Autolamp Delay Input Circuit Short to B+ LCM GO to Pinpoint Test F . B1695 Autolamp ON/OFF Short to B+ LCM GO to Pinpoint Test F .

SOURCE: tail lights
I had this same problem with a nissan. When I hooked up the aftermarket stereo there was a wire for lumination and the aftermarket already has this covered so hooking it up blew the fuse for the tail lights.

One of the tail light bulbs can be shorted internally. Replace the tail light bulbs first. Try this cheap fix first.

Before going ahead and spending money on a new module, test it first. The module is located under the steering column. You'll find a Brown wire on one of the connectors (i just looked at a wire diagram). Do no disconnect anything. Back probe the brown wire, which is the power feed to your park lights. With the lights off, there should be 0 volts on you voltmeter. Turn the park lamps on, There should be 12V. If there is not 12V, disconnect the connector and try to check voltage at the pin that feeds to the brown wire, if still not 12V, replace the module. If you do get 12V, then module is ok, find where the 12v is being dropped before making it to the lamps.

Is the fluid full enough? there should be a dipstick to tell where the level should be. Also is the belt tight enough? Wires loose?
