I have a 94 Explorer headlights will not go out even when ignition is off and key out.

Headlamp Delay System - Autolamp, Aerostar and Explorer
The autolamp system provides light sensitive automatic on-off control of the exterior lamps normally controlled by the headlamp switch . The autolamp system keeps the lamps on for a preselected period of time after the ignition switch (11572) is turned off. The preselected time lapse can be adjusted by the operator up to three minutes.
On Aerostar, the system consists of a light sensor amplifier (13A018) , automatic headlamp dimmer relay (13A025) , and a time-delay headlamp dimmer sensor control (13C105) which includes an ON/OFF switch.
The Explorer consists of an ON/OFF switch, a light sensor and a time delay control which are part of the inside rear view mirror (17700) and two automatic headlamp dimmer relays .
Connections to the vehicle lamps parallel the connections to headlamp switch requiring the headlamp switch to be turned to the OFF position for the automatic control feature.
In normal operation, the system will turn the exterior lamps on when the natural outside light available to the light sensor amplifier decreases below a predetermined level, such as at sunset. Also, the lamps will automatically turn off when the level of outside light exceeds a predetermined level during daylight hours.
On Aerostar, the light sensor amplifier is mounted under a group of slots in the upper instrument panel in front of the driver. The light sensor amplifier must always be exposed to outside light to function properly. Do not place any items over the group of slots in the upper instrument panel which may block light to the light sensor amplifier.
On Explorer, the light sensor amplifier is on the back side of the interior rear view mirror. Do not place any items on the mirror that will block the sensor.
The headlamp dimmer sensor control thumbwheel is located next to the headlamp switch for Aerostar and on the interior rear view mirror for Explorer. The autolamp system is functional for automatic operation when the on-off control is moved from the OFF position. The closer the control is moved toward the max-delay, the longer the lamps will stay on after the ignition switch is turned off.
Pulling out the headlamp switch will override the autolamp. Automatic operation will not be possible until the headlamp switch is turned off.
Can you operate the headlamps manually, do they work ok? I don't like auto-lamps. Just my opinion.
I thought the above info might help?

Where is the dome light switch on 2003 neon ? The dome light does not come on when the front driver side door is open. There is no visible dome light switch in the door jam like most vehicles. Where is it...

The dome lamp receives power from the 10 amp micro fuse located in the Power Distribution Center (PDC) on the M1 circuit. This circuit is HOT at all times. The ground path for the lamp is provided in two different ways.

One way is through the door ajar switches. Circuit M2 connects to all the door ajar switches from the dome lamp. The switches are case-grounded to the body. When a door is opened, the plunger in the switch closes, completing a path to ground.

The second ground path is through the headlamp switch. Circuit M2 is spliced in with the door ajar switches. When the operator turns the headlamp switch to the dome lamp ON position, a ground path is provided through the switch on the Z1 circuit. This ground terminates at the instrument panel left center support.

The time delay relay is used to allow a time-ON function for the ignition switch lamp. Power for the relay is received on the M1 circuit from the 10 amp fuse located in the Power Distribution Center (PDC ).

When a door is opened, or the headlamp switch is moved to the dome lamp position, a ground path is provided for the relay on the M2 circuit. This energizes the relay, closing the contacts. When the relay contacts are closed, power is provided through the relay to the M50 circuit.

The M50 circuit supplies current to the ignition switch lamp in the steering column. Ground for the lamp is provided on the Z3 circuit. This circuit splices with the glove box lamp, the ash receiver lamp, and the PRNDL lamp. The Z3 circuit terminates at the instrument panel left center support.

So, I would check the time delay relay since it supplies power to the circuit. Also, check for a good ground at the instrument panel left center support.

The parking lamp fuse is engine compartment Fuse # 6
After the main headlamp switch the cab fuse panel fuse # 18 is the fuse for the instrument illumination.

Don't forget to turn the main headlamp switch to at least the park position when you test the fuse with a meter.

    2004 crown vic interior lights stay on

    Don't think you have a door ajar switch problem , more then like the lighting control module is the culprit . Does the door ajar light on the instrument cluster stay lit ?
    The interior lighting can be separated into two distinct modes of operation: the courtesy lighting and the demand lighting. The lighting control module (LCM) controls all of the interior lighting in the vehicle, as described in the following text.
    The front dome lamps, rear reading lamps, and instrument panel courtesy lamps, can be illuminated either by opening any of the vehicle doors (courtesy lamp function) or by depressing the headlamp switch (demand lamp function).
    When any door is open, the door ajar switch grounds an input to the LCM which then sends power to the courtesy lamps. The voltage sent to the courtesy lamps gradually increases from 0 volts to 12 volts within 500 ms (± 50 ms), to achieve the theater lighting effect. When the door(s) are closed the door ajar switch(es) break(s) the ground to the LCM input which then gradually reduces the power from 12 volts to 0 volts within 5 seconds. (± .5 second).
    When the headlamp switch is depressed it grounds an input to the LCM which in turn sends 12 volts to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps. When the headlamp switch is depressed a second time, it breaks the ground to the LCM input which then ceases to send power to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps.

    The battery saver will disrupt power to the courtesy lamps after 10 minutes, the demand lamps after 30 minutes, and the headlamps after 10 minutes. Turning the ignition switch to the RUN or ACC position will terminate the battery saver feature by disabling the interrupt timers and reinstate power to the lamps.

    • Are the courtesy lamps still illuminated after the 25 second time-out period?
    Yes GO to C2 .

    No The system is operating correctly. C2 TEST DOME LAMP SWITCH Depress the dome lamp switch.
    • Are the courtesy lamps still illuminated?
    Yes DEPRESS the dome lamp switch a second time. GO to C3 .

    No The system is operating correctly. C3 CHECK THE LIGHTING CONTROL MODULE

    • Are the courtesy lamps still illuminated?
    Yes REPAIR circuit 53 (BK/LB). REPEAT the self-test. CLEAR the DTCs.

    No INSTALL a new LCM. REFER to Section 419-10 . REPEAT the self-test. CLEAR the DTCs.

    Dash and shifter lights in 1996 jeep cherokee wont light

    Hello and welcome to FixYa . Locate the dial that controls the brightness of the dashboardlights. If the control is not immediately evident. Make sure the brightness control is turned on. If it is and the lights aren't working, the problem may be a bad fuse. Check the fuse that controls the dashboard lights Replace the fuse if necessary. If just one part of the instrument panel is not lighting up, then you have either a burned-out bulb or a wiring problem.
