There is actually a modual that runs the lights... the lighting control modual (LCM) not saying this is for sure, but a good place to start. keep in mind if u replace the modual, you have to have it flashed(programmed) to the vehicle.hope this helps and good luck

Problem i am having is a no headlight issue i replaced my icm about a week ago and now i have no lights at all no dash lights no running lights no high beam lights


As far as interior lamps, there may be an interior dimmer, it rotates to increase or lower interior lamps, and usually includes the dash lamps.
If the lo beams work but not the hi beams, have to check headlamp dimmer switch.

Why wont the headights or running lights work on my 2002 Buick LaSabre?


There are several reasons why your headlamps an running lights don't work , the headlamp switch is a good one ,plus relays an the DIM - dash integrated module an associated wiring ! Here is how the headlamps work , right out of Buick factory service info !
The dash integration module (DIM) provides battery positive voltage to the signal circuits of the headlamp switch. The signal circuits include the headlamp switch headlamps on signal, the flash to pass switch signal and the high beam input. With the headlamp switch in the ON position, a ground path is available for the headlamp switch headlamps on signal circuit of the DIM through the headlamp switch. The DIM provides ground to either the headlamps high beam relay control circuit or the headlamps low beam relay control circuit of the low beam circuit. The position of the headlamp dimmer switch determines which relay control circuit has ground. The DIM supplies battery positive voltage to the relay control circuits, if the headlamps are necessary. The fuse block - underhood supplies battery positive voltage to both relay switch circuits. When the low beam relay control circuit is energized, current flow is to both low beam fuses and to the low beam headlamps. The headlamps have ground at G103 and at G401. When the headlamp high beam relay control circuit is energized, current flow is to both high beam fuses and to the high beam headlamps. The high beam circuit is divided into a left and right side circuit. The current flow of the left high beam is from the fuse to the left high beam lamp. From the lamp, the current flows to the normally-closed contact of the DRL relay to G103. The current flow of the right high beam is from the fuse to the right high beam lamp. From the lamp, the current flow is to ground at G401. When the headlamp dimmer switch lever is pulled toward the driver, the flash-to-pass switch closes. This grounds the DIM flash to pass switch signal circuit. In response to this input, the DIM energizes the HDLP HI BM relay. Both high beams remain on until the driver releases the switch handle. If the low beam headlamps were on during a flash to pass operation, the low beams remain on. The headlights may be switched to high beam with the opposite movement of the headlamp dimmer switch lever.
By running lights , do you mean park lamps or day time running lamps ?
Park, Tail, License and Marker Lamps
The park lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The fuse block - rear supplies battery positive voltage to the switch contacts of the Park LP relay. When the headlamp switch is in PARK or in ON, the park lamp switch on signal circuit of the DIM has a ground path. The DIM provides battery positive voltage to the control circuit of the Park LP relay. When the park lamps and/or the tail lamps are ON, the DIM energizes the park lamp relay control circuit. This closes the switch contacts. Current flows from the Park LP relay to the LH PARK LP and the RH PARK LP fuses. From the fuse, the current flows to the park lamps. The left park lamps are grounded at G103, G401 and G402. The right park lamps and the right tail lamps are grounded at G103 and G401. The DIMR fuse supplies battery positive voltage to the license lamps and to the DIM instrument panel lamp fuse supply voltage - 1 circuit, for interior lamps dimming. The license lamps are grounded at G401.
The best advice I can give is that you take this to a ASE certified professional repair facility unless your a qualified automotive electric repair person !
Diagnostic Starting Point - Lighting Systems
Begin the system diagnosis with the Diagnostic System Check - Lighting Systems . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

My headlights don't work, but the brights do. What caused this and how can I fix it?


Every headlamp has a bulb inside that has two filaments one for high beam and the other one for low beam, if any of those filament is cut then that beam (High or low) won't work. If your high beam work then your fuse it's ok, so you can visually inspect your headlights bulbs for broken filaments. remove bulb socket and remove the bulb carefully to inspect the filaments. if the filaments are atacched from one terminal to the other then the bulb it's ok, if not replace the bulb.

98 ford lariat. Headlights stopped working. running lights come on and brake lights and turn signals. checked all fuses under dash and under hood, pulled out headlight switch and it looks fine. note only...


Is this both the high beams and low beams that do not work ?

If you checked all 3 fuses with a meter ( with the headlamp in Low position for both low beam fuses or in high for the high beam fuse ), the next items to test are the MFS ( MultiFunction Switch ) and the main headlamp switch ( test not look at it ).

I have a 92 VW Golf, and I cant get the low beam headlights to come on, or the interior dash lights to come on either. The High beams will come on, and the rest of the lights work fine. Only the dash...


Sounds like you have a bad headlight switch. I would also check fuses 1&2 in the fuse box, those are for the low beam headlights, and fuse 3 is for the instrument panel lights and the license plate lights. All 3 should be 10 amp fuses.

1994 ford f-150 with day time running lights headlightnot working


Daytime Running Lamps
The daytime running lamp (DRL) system is designed to turn the high beam headlamps on, with a reduced light output, and without illuminating the high beam indicator lamp in the instrument panel. You have a DRL Module.
The multifunction switch is the stalk on your column.

This is 96 F150 circuit. Don't have 94.

My car has fog lamps


FROM THE OWNERS MANUAL
Foglamp control (if equipped)
The headlamp control SWITCH also operates
the foglamps. The foglamps can be
turned on only when the headlamp
control is in the , and
position and the high beams are not
turned on.
Pull headlamp control towards you
to turn foglamps on. The foglamp indicator light will illuminate

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.
