No power to right side (PS) headlight low beam plug socket, new bulb, fuse is good. High beam works, blinker works, park light works. just no low beam and doesn't register any voltage on volt meter.


check low beam fuse when switched on if it has voltage registering across the fuse ,if there is voltage across the low beam RHS fuse then it is possibly a pinched wire from the headlight running back towards inside of the car

Headlights wont come on


some times just the low beam filament in the bulb will blow out and the high beam filament will continue to work. Buy new bulbs.

Lt. headlight low beam wont work after replacing the bulb.


I assume it didn't work before you changed the bulb either. You'll have to check for voltage at the bulb socket when the low beam headlights are turned on. If there is none you'll have to trace the wire back to where it splits from the right low beam headlight. If there is voltage there you have a problem with the new bulb.

Low beams do not work, both left and right. high beams do work. Fuses checked and are good.


I would test the sockets/wiring with a multimeter. Sometimes a bad low beam bulb could cause this issue. See if your getting voltage at the headlights.

Sounds like you need a bulb,the daytime running lights send power to the high beam wire so they look like low beam lights are on but really they are high beam lights running on low voltage.

My 1992 Corolla DX headlights won't come on! I have changed the fuses and the bulbs. The relay clicks when turning the switch and the wiring seems to be in good condition but I am no electrician. The...


Power flows from the battery to the main fuse. Then it flows to the control coil and contact side of the headlight relay. When you turn on the headlights, the headlight switch provides ground to the control coil in the headlight relay and that operates the contacts. The contacts allow power to flow to the right and left hand headlight fuses. Power flows to the headlights. The headlight switch is what provides ground to the high and low beams on the headlights.

To diagnose, remove the headlight relay. Using a voltmeter, check for battery voltage on terminals 3 & 4 in the socket with the key in the RUN position. Then turn on the low beams. Test for good ground on terminal 1 in the socket. If you're not getting ground, then you've got a problem with either a bad headlight combo switch or a bad ground. If you get good ground on terminal 1, reinstall the relay, turn on the low beams and test for power in the headlight sockets. If you get battery voltage, that confirms you've got good fuses and wiring up to that point. Next, check for good low beam ground on the red/green wire in the bulb socket. If you're not getting good ground, it's either a bad combo switch or bad ground from the combo switch. Then turn on the high beams and check for good ground on the red/yellow wire in the bulb sockets.

It wouldn't hurt to clean the ID ground on the left side of the instrument panel, but based on everything you've said so far, this sounds like a bad combo switch

There are fuses for left and right low beams. Headlights on low beam, use a test light, see if voltage on fuse circuit? If no voltage that will lead us back to dimmer switch or problem with wiring circuit from dimmer switch.

It is entirely possible for both low beams to be out have you verified that there is No voltage on the low beam electrical circuit of the headlights?
