Check fuse and relay, if its good, than you have faulty switch, only work on low but not high beam, to turn high beam on the switch move forward which is fauty or no contact, flashing high beam move toward you which has a good contact and working. it two switch in one unit.

Left operating headlight not working


the switch supplies power to the relays that switch on the lights according to the position you have it at
so on high beam there will be 2 high beam lights working
on low beam there will be 2 low beam lights working
back to passing lights or flashing head lights , both beams will work so the switch is the last item to consider
Now with only one side beam not working it comes back to the ground on that light for that bulb
remember that electricity follows the path of least resistance so it the ground is bad the current will ground out through another point including a light which will switch that light off or make it not work
remember the brakes light that flask when an indicator is used --same thing

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.

No high beams


  1. If the flash to pass function makes the high beams come on, then the high/low beam switch needs replaced.
  2. There is a high-beam relay in this car that controls when the high beams come on, which should be when you operate the switch.
  3. Although, not usually the case, both bulbs' high beam filaments could be out. Replace one bulb to see if that fixes the problem for that bulb.

I have a 2005 chevy Impala SS and my high and low beams go on at the same time and three of them are dim.


Hello! The "Flash to pass" switch in the Headlight dimmer switch is the most probable cause...When it is activated it turns off the low beams...The dimness can be attributed to a resistive ground in that circuit...but one thing at a time...The turn signal multifunction switch contains the flash to pass switch...Therefore you would replace the multifunction switch...See picture below...Guru...saailer

Ensure system LED flashes once and an audible warning sounds. Operate headlamp high/low beam switch to flash high beam position 5 times. Ensure system LED flashes once and an audible warning sounds. Programming mode activated: Press and release lock or unlock button on first key. Ensure system LED flashes once and an audible warning sounds to indicate correct programming. Repeat programming procedure for remaining keys. Switch ignition OFF and remove key. Close driver's door. Check operation of keys. Keys can also be programmed using diagnostic equipment

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.
