Hello,

I changed the bulb and every­thing looks good, but the low beam would not work.

I'm thinking this is a pigtail problem, but just wanted to check with the experts to make sure.

Thanks,

Roosevelt.

Hi,

Each light has two fuses, one for low and one for high beam. Locate the fuse box under the hood.

Locate fuse EF23. That fuse is dedicated to the left low beam only. See pic below. When you check the fuse, make sure power is present on both sides.

Here is a link you may find helpful:

Also, the headlamp low beams must be on for power to be present at the fuse.

Let me know what you find.

Take care,

Joe

Hi,

No problem whatsoever. Let me know. I have no idea why each light and each beam has to have its own fuse, but that's what they did. LOL

Take care,

Joe

Hello Joe,

I replaced the 10A fuse that's for the Driver's side headlight, but still it does not operate, Either in daytime headlight mode or when headlights are on. The high beams work though.

Is it time for an electrical check at a repair shop?

Thanks for your help.

Roosevelt.

Hi,

If the right low beam works, then either you have a faulty bulb, a wiring problem, or a connector issue. I say that because although both left and right low beams have their own fuses, power comes from the same place. The low beam relay.

Were you able to confirm there is power present at the fuse?

Let me know.

Joe

Hello,

The new bulb worked for a day then stopped working. I have not tested to see if power is at the fuse. I can buy a fuse tester for this, correct? I will get one today and let you know.

Thanks, Roosevelt

Hi,

I believe a fuse tester will only test the continuity in the fuse. We need something like a test light, voltmeter, or multimeter to determine if power is present.

Take a look through this link:

Let me know what you find.

Hello Joe,

The pigtail behind the headlight was the issue. Replaced it, and everything is good.

Thanks for your help,

Roosevelt.
