What to do if your headlamp relay is not working?
Check the voltage at the dimmer switch. Youll see it on the steering column a rod goes down to the 3 wire switch. Youll need a test light to check your voltage with. helpful? helpful? If the relay is the problem, just unplug the old one and plugin the new.
How to wire a headlight enhancement relay kit?
This video is a detailed walkthrough of the American Autowire headlight enhancement relay kit. Our kit includes separate relays for the high and low beams as well as upgraded GXL wire to make fresh connections to your lights. It’s available in both standard (pn/ 500403) and weatherproof (p/n 500431) form. Loading…
Where is the headlamp relay located on a car?
The headlight relay is located in the left instrument panel fuse block, on the left side of the instrument panel, and the daytime running lights relay is located in the underhood compartment fuse block, which is located in the engine compartment.
What can cause a low beam headlight to be dim?
If it is, use a voltmeter to see how much power, if any, is reaching the headlights. If there is no power reaching them, there is a break in the wiring somewhere between the fuse panel and the headlights themselves. Thanks! What can cause the light to be dim except when on the high beam setting?

What causes a headlight to stop working after blowing a fuse?
The next video shows you how a blown fuse can affect one headlight. When handling a light bulb, never touch the surface of the bulb. The oil from the skin on your fingers, combined with the high working temperatures of the bulb, will reduce the bulb’s service life or cause it to shatter sooner. 2. My Headlights Flicker
How can I get dipped headlights when fuses are OK?
Turn on the ignition. RELEASE the heated rear window switch (an acoustic signal will sound if activation has been performed correctly) OPERATE the heated rear window switch 6 times (the main beam headlamps switch on and off automatically)
What to do if both side of Your Headlights are not working?
Neither side works: If both headlights are dead, it’s probably not a problem with the bulbs, but it’s worth a check. The most likely scenario is that the fuse is bad. Remove the fuse for the headlights and check it. When a fuse is bad, it’s obvious because the filament will have a gap in it.

Why are my headlights not working in high beam?
If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
Why are my high intensity discharge ( HID ) headlights not working?
High intensity discharge (HID) headlights can also fail due to other associated components. Neither of the headlights work. The cause: Burned out bulbs, or an issue with power or ground. The fix: Check for power and ground, and fix if necessary. Otherwise, replace the bulbs.
If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
Is there a way to fix a faulty headlight switch?
It is not advisable to endeavor to fix wiring problems on your own. The Cause: Faulty relay, module, dimmer switch, headlight switch, etc. The Fix: Replace the faulty components.
Where are the relays on a car headlights?
Thankfully, there is a simple solution to get full system voltage to the headlights — All it takes is a pair of 30-amp relays, one for the low beams, and another for the high beams. This works because a relay, mounted near the headlights, will pull power directly without losing voltage through the headlight switch.
Can a headlight switch be upgraded with a relay?
Relay Upgrade Bonus: Your headlight switch’s life will be greatly extended because the heavy current is now channeled through the relay — the headlight switch will now only trigger the relay with a very low current load.
Why are my low beam headlights not working?
Both low beam headlights are not working. I have changed the bulbs and checked the fuses and it’s still not working. High beams work fine. What is odd is that when turning the switch to low beams the high beam light on the dash comes one. As the high beams work I don’t think the relay is bad. But I could be wrong.
