SOURCE: DRL and High Beam do not work right on Honda Accord EX 1998

Some time back I found some data on a similar website suggesting that the Day Light Running circuit board, just under the steering column, developed cracks in some of the soldered joints. Your high beams should also be affected with loss of day light running lights.
Resoldering repaired the continuity of the circuits. Ours is now working quite reliably. Some of the defective areas developed slight brownish discoloration, that's how I was told to recognise the areas to be resoldered. Hope this will help you solve your problem.

High beam headlight relay located


there is a fuse for that circuit in the fusebox lower dash if this is ok check that your getting power to the high beam wire at bulb holder if not the part of switch for high beam isn't working if are getting power check the bulb holders for warping etc as can get very hot and mishapen so that the bulb doesnt always sit on the contacts but if bothe lights out i'd think its a power supply problem

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

Headlight problems


Hi. That sounds like the Low/high beam switch is malfunctioning and in need of replacement. I believe this because the headlights will not come on no matter which power source is attempting to activate them. Clearly, they are not getting power. Since the high-beam indicator light is functioning and indicating HIGH BEAM it IS getting power, There is no further interruptions in that circuit, save the fuse. IF the fuse is good,.. tested good.... Then the switch is bad, if the fuse is bad... replace it. If this doesn't solve the problem You have blown all your headlights simultaneously, or lost all the connectors to the headlights all at once, or possible got so unlucky as to lose all connectivity to just the headlights magically. I'd bet the fuse if I didn't believe that you would have checked that before posting the question here, and that doesn't account for the indicator to be stuck, so.... This pretty much leaves the switch ol buddy, sorry.

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

1994 Mercedes c280 high beams not working...


At first 1994 C280 high beams began to not connect regularly when stick pushed forward, then not at all. Drove high beams by pulling and holding stick back towards steering wheel until that stopped working, too. Shop said the turn signal switch was at fault-- had seen it many times before with W202; about $160 to replace. Haven't done it yet, but should be an easy fix?

I have a 1998 cavilier i have no low beams,fuses checked good


 I’m inclined to believe you have a headlight switch problem and here’s why. There are 2 fuses one for each of the headlights on the vehicle. For the daytime running lights (DRL) to operate the fuse and wiring to the right head light has to be good, because it supplies the power for both headlights in the DRL mode. The fuse and wiring for the left headlight has to be good because the DRL relay needs power from that fuse to operate. The DRL relay in turn provides a path through the left headlight and wiring to ground. When you pull back on the dimmer switch, you are activating the flash to pass circuit of the headlight switch assembly. Because the flash to pass mode works you then know that the high beam wiring and headlight bulbs are in good condition. This also tells you that the ground circuit for the headlight switch is good. In many newer vehicles, the headlight switch doesn't provide power to the lights. The headlight switch has now become the path to ground to complete the circuit. The headlight switch and the high/low beam dimmer control are one assembly so when you replace one you get the other free. Such a deal! My coffee bet is on the headlight switch assembly.
