Four cylinder front wheel drive automatic 34,000 miles.

I have one lowbeam headlight out. I replaced the bulb and relay in the fuse box in the engine compartment, but it still does not work. I do not know what I should check next.

Please furnish this information. This will help narrow down the troubled circuit. Any other information that you can furnish will be very helpful.

1. Do you have automatic lamps? Light turns on automatically when the ignition is on.
2. Do you have daytime running light? Headlights turn on once the vehicle is in motion.
3. Explain which low beam light does not work? Driver or passenger side.
4. Turn on your high beam. Do you have both high beam lights? If not, which one burned out?
5. Do you have fog lamps? If yes, is the fog lamp operation affected by the problem you are having. If yes, describe in detail.

If you have checked low beam fuse 15 amp and low beam relay (junction box under the hood) and headlamp fuse 10 amp under left side dash, the problem lies within the wiring into your driver side low beam head lamp. Verify that your new headlamp is bulb number H7, and it is plugged in properly, with the spring clip safely fasten. The bulb can only go in one way

If it still does not work, remove the low beam wiring harness from the bulb. Using a digital volt meter, attach the leads to the wiring harness, red to yellow, black to black. With the headlight switch on, you should have twelve volts. If you do, bulb is bad, if you do not, wiring is bad.
