If everything else checks out as you say then there may be a bad/loose connection somewhere in the wiring and would have to be traced from switch to both headlamps if your daytime running lights and headlights (with switch turned on) works intermittently. and/or your switch itself may be starting to go bad (bad contact, etc.) and would need to be replaced. hope this helps

Low beam head lights not working - The low beams, both stopped working. The high beams work fine. I checked the fuses and all 4 are good. I even swapped the low and high beam fises just in case. No...


if the fuses are good then you need to check for power and ground at the headlight plug that attaches to the headlight bulb if you have a good power and ground there and the connections are good then the bulbs are both no good.or if you can tell the bulbs are burnt out by looking at them then you don`t have to check powers and grounds.you also can directly feed power and ground to the bulb and check both the terminals for high beam and low beam as you cannot tell which is which by looking at the terminals

My low beams don't not work, only high beam. All other lights works fine. Problem started without any known issue. They were working just fine two nights ago. Where should I start? Is there a fuse or relay...


on a lot of vehicles theres a fuse for low and high beam headlights. could be a relay also. check the fuses in the fuse box. if both headlights have been changed and the fuses or relay are ok, then the problem is either in wiring or a bad dimmer switch. have a good day !!

Both of my low beams just stopped working at once. High beams work fine, and bulbs seem to be good. We've replaced the fuses also, and it hasn't worked. what would cause the low beams to both just quit...


The headlight relay has probably failed. This relay is in the underhood fuse box. There are typically two of the same relays in there, so you can swap the low-beam relay for the high-beam relay to verify the problem before you shell out $30 for new relay.

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

High-low beams not working


Check for headlight relay and fuse. Some cars have separate circuits for head light flasher and normal high/low beam. From your description, I would suspect a bad connection to/from relay or relay itself.
