Check switch itself likely it is worn out. also check lights for good ground and high beam switch. Most likely its the switch.

First of all are your headlights a double filament type headlight? If yes then I would suspect that a power wire to the high beams is broken or shorted. If your high beams are a separate set of lights from your regulars running lights then either the high beams headlights are missing. or has a broken power wire or shorted or...You could check the fuse box under your dash and under the hood of the car to see if you have a fuse for the high beam lights.

Dash lights go on and off while driving, then headlights do the same


Test the electrical circuit's ! Look at a wiring diagram so you know what wire's to test . Watch these video's , buy a DVOM - digital volt ohm meter . Learn to test so you don't listen to guesses .
Basic Electricity for Service Techs Ohm law Current Flow Opens Shorts
Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia
Electric Testing Techniques You Need to Know Free wiring diagrams here . http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size. Under system click on lighting ,then under subsystem click headlamps . Click the search button then the blue link's . Right away in the first diagram i see the headlamp / panel dimmer switch is a input to the BCM - body control module . I mite think your first response would be to want to replace the BCM ! Reading a discription of how the lights are suppose to work may shed some light on the problem .
Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch on input circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor.
If the headlight switch is left in the ON position, the inadvertent power control feature will turn off the headlights approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the headlights will remain on until turned off or the battery runs dead.
The high beam indicator is illuminated when the instrument cluster receives a class 2 serial data message from the BCM that the high beams are illuminated.

Having the vehicle checked for DTC'S - diagnostic trouble codes , BCM - codes ! Need a professional type scan tool . Part stores can't read body codes , dealer or independent repair shop .

DTC B2575
When the body control module (BCM) senses a request for low beam headlamp illumination, the BCM sends a ground signal to the low beam headlamp relay through the headlamp low beam relay control circuit. The headlamp low beam relay will apply voltage to illuminate the headlamps.
DTC B2580
When the body control module (BCM) receives a ground signal from the multifunction high beam or flash to pass (FTP) switch commanding to illuminate the high beam headlamps, the BCM will energize the high beam relay by grounding the high beam relay control circuit.
DTC B2600
DTC B2610
The body control module (BCM) receives a variable voltage signal from the instrument panel (I/P) dimmer switch requesting to illuminate the illumination lamps to a desired intensity. When this occurs, the BCM directly sends a variable voltage based on the I/P dimmer switch position on the instrument panel lamps dimming supply voltage circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuit.
Voltage for the instrument panel lamps dimming supply voltage circuit, instrument panel lamps dimming control circuit, and the LED dimming signal circuits is from the TBC 2 A fuse in the instrument panel fuse block directly through the BCM to these circuits.

DTC B2620
The BCM directly sends a 5 volt reference voltage to the I/P dimmer switch which is then adjusted based on the I/P dimmer switch position and returned as a dimming return and dimming input to the BCM. The BCM uses this signal to directly control the desired level of instrument panel illumination lamp intensity.

Your best bet , take it to a qualified repair shop .

Does this model use a 4 headlight bright system? I have 2 low beam lights but when I put on the bright lights the 2 low beam lights go out and only the 2 bright lights stay on.


I think that many 1990s and even some 1980s GM vehicles with seemingly 4 headlight systems actually use only 2 at a time.

My 1990 Oldsmobile Cutlass Calais, for instance, had 2 high beams that went on independently of the 2 low beam lights when switched with the turn signal lever.

In the 1970s the GM vehicles had 4 headlight systems where all 4 headlights would go on, but they used sealed beams rather than the capsule lights that are used nowadays.

For instance, our 1976 Cadillac Seville has a 4 headlight system that lights up 4 headlights on the high beam mode.

Good luck on seeing at night with the current set up.

Green light on instrument panel


Hiya--the green headlamp logo on the instrument panel comes on automatically after you start up the engine.
The green light comes on when your headlight switch is on 'auto' until you turn it to 'parking lights' or 'full on' function, that'll turn off the green light...it's normal.
The other thing is if one of 2 headlight bulb reach the end of bulb life, the green light will flash on/off a few times then stay off....until you or the garage shop put in new headlight bulb.

Headlights wont work


Well...lets start with the obvious. Check fuses and NEVER piggyback any stereo or security stuff into their fuses...you dont want the lights to shut down during a night drive!!
Check under the hood for a relay center...also has some fuses there as well.

The Daytime Running Lamps are a "straight through wiring configuration". Doubt it even goes through a headlight switch at all.
But the regular lights do.
Unless you've worked on the front of the car and forgot to plug the headlights back in, do this...
Turn the light switch on...looking at the instrument cluster , can you make the high-beam-indicator light come on?
As you rotate the headlight switch knob...does the instrument panel lights brighten or dim? You probably have a faulty headlight switch...auto stores have them...they simply plug in.

Instrument Cluster lights do not go on, emergency lights steady- Sable 2002


Has anyone figured this problem out? Our 2002 Sable just started this as well...instrument cluster lights out, turn/hazard lights on when the headlight switch is turned on. This has the auto on/off switch with fog lights. This is happening in the auto and manual on mode. Any solutions would be appreciated.<br />
