Question about 1992 Oldsmobile Ninety Eight Regency

1 Answer

1992 olds regency headlight problem

Only the bright lights work. the dimmer has been replaced, as well as the headlight switch. I have checked the fuses under the hood. I don't know where the relay is. It has the twillight sentiel switch and it appears to still function. I have continuity from the headlight socket to the battery terimals. But I have continuity from both termiinals to one terminal on the headlight socket... What 'cha think?

Your alternator may be going bad. Test your battery while it is running with a voltmeter. It should be above 13.0 volts. I would check that first.

get yourself a wiring diagram to see what powers up the relay, it is a fuse, have you checked the fuses? also these pumps short out and that is why it is not working and blown out the circuit, replace it before you do anthing, also remember that the pump is powered up by the PCM only during cold start, so 99% of the time it has no power to it.

My headlights wont work


I don't believe there is a fuse. There is a circuit breaker built into the headlight switch. If you are sure the headlight switch is good, it could be a bad dimmer switch. If you have a voltmeter, with the headlight switch turned on, a larger yellow wire going from the headlight switch to the dimmer switch should be a hot wire. The dimmer switch sends power on a tan wire to the low beams, and through a light green wire to the high beam bulbs.
If your high beam indicator on the dash also doesn't work, then it is likely one of those switches. A voltmeter or test light would need to be used to find which one is bad. If you can find the connector at the steering column going to the dimmer switch, pull it apart and check for power on the yellow wire coming from the headlight switch, with the headlight switch turned on. If no power, the headlight switch is bad. If there is power there, then the dimmer switch must be bad.

Check your dimmer switch. When a dimmer switch goes bad only one set of lights work being either the bright or the low beams.

Dash lights do not work 2000 ford exploier


All go out at once, first check fuses,then dimmer switch for dash lights, finally headlight switch. To check dimmer switch, pull connection off back, on harness with test light and headlight switch activated, 1 of the leads should have power, if so, use ohm meter on dimmer to make sure it has reading between 0 and some value, if no value, open, dimmer is bad, if there wasn't power then check headlight switch, there should be heavier gauge wire that powers switch and 1 for output to hi/lo switch, smaller gauge wires for tail lamps, dash lights, license plate lamps, parking lights. The color wires from dimmer would correspond to the same colored wires on headlamp switch, probe that connection on headlamp switch with switch engaged and see if you have power, if not replace switch, if so, check wire from switch to dimmer.Now if the lights slowly went from bright one day, to less bright some other day, to not working, then the bulbs are bad... good luck...

Two things you need to check. 1)check the grounding. A poor grounding almost always causes any light to be dim including your headlights. 2)Your dimmer switch has a potentiometer which could be corroded or a bad resistor in the switch.

The headlights only work on Bright. The dim


If the low beam head light relay is fine,and the dimmer switch checks out fine,then look at the out put wire from the dimmer switch to the head light relay,check for voltage,then check the relay to see if it energizes.Then follow the wire(out put)from the relay to the head light.Now if power from the dimmer is getting to the relay,but the relay is not energizing,look for a bad relay,or bad relay ground wire.

Tail lights don't work when bright lights are on. dash lights don't work when dims on


Sounds like you have a problem with a ground. Electrical wierdness like this can almost always be attributed to a bad ground. Have you done anything to the car recently that could have affected a ground? Replaced the dimmer switch or light switch?
