High beam is working fine but the low beam isnt working. I checked the fuses for the low beam. I checked the ends where the fuses go in to see if there is any current but there is none. (I turned the low beam on and checked with the multimeter). I would like to know if there are any other fuses to be checked. Where is the headlight relay switch? THanks.

More than likely this is a headlamp relay or the dimmer relay.

The way this works is the head lamp relay powers the dimmer relay when you turn the head lamps on.

However, when the head lamps are off, you can see that the relay is in the off position. However, this means the DRL circuit is powered, and the head lamps should be on.

When the dimmer relay is energized the two fuses for the head lamps (not the DRL fuses) are powered.

So, if you have no power on these fuses then I would suggest replacing the dimmer relay.

If the relay is fine, then the switch is most likely the issue.

Please run through this testing and let us know what questions you have. Thanks
