Probably a problem with the LCM - lighting control module . The main light switch is a input to the (LCM) . Here is free wiring diagrams http://www.bbbind.com/free_tsb.html Enter your vehicle info. Year , make , model an engine size . Under system click on lighting , under subsystem click on insturment panel lamps . Click the search button then the blue link . Do you know how to test PWM ,this is how the LCM controls the lights .
Pulse-width modulation Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors an lighting .

Headlights stay on when engine and light switch are off


You need to look at a wiring diagram to see what controls the head lamps ! Could be a relay's contacts are stuck shut causing lamps to stay on or could have a LCM - lighting control module shorted internally . The head lamp switch could be the problem . Do you know how to read a wiring diagram ? Do you know how to do basic automotive electrical testing ? You can check out such videos on you tube > Go http://www.bbbind.com/free_tsb.html for free wiring diagrams .

As far as the lighting problem goes ,looking at a wiring diagram I see they are controlled by a electronic control module .(LCM) - lighting control module . Checking power and grounds for the module and inputs from the main light switch would be a good place to start . Looking at a wiring diagram so you know which wires to test .

Can't turn off headlights on 2001 crwn victoria polce intercepter


I hate to say this but it sounds like the dreaded expensive LCM, Lighting Control Module. It is the common cause. New is $550. It is above the brake pedal and steering coumn under the dash.

There is a guy on ebay who fixes them and sells you the last one he fixed. Then you send yours back for a core charge refund. He is in California.

Here is what it controls. DO you have auto lamps? Also, pleae rate this help, thx

Lighting Control Module (LCM)
The LCM eliminates the electronic interference and heat associated with the thermoelectric devices used previously. The LCM is a microprocessor- based module that controls several vehicle subsystems. It responds to electrical input signals from various switches, sensors, and external modules.
LCM subsystem functions include:
  • headlamps with autolamps
  • turn signal lamps/hazard flasher lamps
  • cornering lamps
  • parking lamps
  • courtesy lamps
  • demand lamps
  • battery saver
  • backlighting
------------------------------------------------------------
The system consists of:
  • a light-sensitive light sensor amplifier
  • a lighting control module (LCM)
  • an autolamp time delay control (part of the headlamp switch and includes an OFF position)
------------------------------------------------------------------------------------------------------------------
see owner manual for fuse box location
  • The autolamps are inoperative - the autolamps are always on
  • CJB fuse 21 (15A).
  • Circuitry.
  • Autolamp switch (part of the headlamp switch).
  • Light sensor amplifier.
  • LCM.

---------------------------------------------------------------------------------------------------------
dealer has scan tool to do this test. About 1/2 hour labor charge.
  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
    • check that the program card is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
  1. Carry out the DATA LINK DIAGNOSTIC TEST. If the diagnostic tool responds with:
    • CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418-00 .
    • NO RESP/NOT EQUIP for LCM, refer to Section 419-10 .
    • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics for the LCM.
  1. If the DTCs retrieved are related to the concern, go to the LCM Diagnostic Trouble Code (DTC) Index.
-------------------------------------------------------------------------
Module -Lighting Control (LCM) Removal and Installation
  1. s1a~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Prior to removal of the lighting control module (LCM), it is necessary to upload module configuration information to a diagnostic tool. This information needs to be downloaded into the new module once installed. For additional information, refer to Section 418-01 .
    Disconnect the battery ground cable. For additional information, refer to Section 414-01 .
  1. Remove the LH instrument panel lower insulator.
    1. Remove the pin-type retainers.
    1. Disconnect the courtesy lamp.
  1. If equipped with adjustable pedals, remove the accelerator pedals, and shaft. For additional information, refer to Section 310-02 .
  1. Position the LCM aside.
    1. Remove the screws.
    1. Release the locking tab.
  1. Disconnect the electrical connectors and remove the LCM.

If you can kick the panel and it work, then there is a loose connection somewhere. Start at the fuse block and make sure you have a good connection there, then move forward.

Headlights won't come on, now car won't start.


It is definitely the Lighting Control Module. Just fixed one for a friend. It has internal printed circuit board failure.
It is easy repair but it is expensive. New are 500. Controls much more than lights. Alarm, air bag, door key pad, etc.

You need to have correct part for 2003. tascafordparts,com has the for about $250.

It's just above brake pedal. remove the sond panel. The module will come out without removing other components.

Headlights cut out after being on 10 to 15 minutes


I had the same exact problem. I found that I could make the lights come on by pushing on the top connector on the front side of the lighting control module (LCM). I pulled the connector off, cleaned it and put it back together with some dielectric grease. Only time will tell if I fixed it. On my car, it would only have problems after the headlights had been on for about 3 hours; kind of hard to re-create.

No high beam headlights 1996 crown victoria


does the flash to pass function work? That uses high beam bulbs.

If yes, I would bet $100 it's the lighting control module. Very expensive. @ $500. Can buy for $250 @ tascafordparts.com.

Sometimes on Ebay for cheap price.

--------------------------------
Lighting Control Module Principles of Operation
NOTE: Due to varying wattage ratings and resulting current draw, certain aftermarket headlamp bulbs may cause the lighting control module (LCM) to shut down the short circuit protection, resulting in the low beams becoming inoperative. Verify that the headlamp bulbs meet Ford specifications.
The lighting control module (LCM) receives inputs from the following:
  • headlamp switch
  • multifunction switch
  • photocell and amplifier
Depending on the inputs received, the LCM will command the headlamps on or off.

Power is supplied to the headlamps through lighting control module Circuit 502 (GY) and circuit protection C in the fuse junction panel. Ground is provided to the headlamp bulb and retainer (13N021) through Circuit 57 (BK).

The lighting control module is located under the instrument panel, to the right of the steering column, under the lower steering column cover.

Removal and Installation
  1. Open hood. Disconnect battery ground cable (14301).
  1. Disengage three pushpins and remove lower driver side intrument panel (04320) finish panel.
  1. Locate lighting control module above accelerator pedal.
  1. Disconnect bottom two eletrical connectors from lighting control module.
  1. Remove two screws retaining LCM to bracket and unclip from bracket.
  1. Remove lighting control module from bracket and disconnect two remaining electrical connectors.
  1. To install, reverse Removal procedure. Check lighting control module for proper operation.
---------------------------------

the module is about 6 inches lng and 4 inches wide and has 3 wire connectors.
