Headlights not wokring?

Good find.

Now, to go one step further, the fuse failed for a reason. Was the connector in good shape? Did you bump anything during the replacement that may have caused the fuse to fail?

Keep ans eye on it. If the fuse fails again, further diagnostics will need to be done to find the issue.

That should have nothing to do with it but you never know.

Keep us updated if it fails again.

It sounds like there is a problem with the switch. If you are sure the bulbs are good, I would recommend checking the switch as well as the multi function switch on the steering column.

This may sound silly but have you checked the bulbs? Many times I get cars to come into my shop with this problem and both bulbs are burnt out.

I would replace them, they have 2 filaments in each bulb and my guell is the low beam filament is burnt out.

Well it sound like the dimmer switch is bad. The lights run through the dimmer from the switch then to the headlights. Here is a pic

Welcome to the forum, I'd check the voltage circuits at the high and low beam relays in the power distribution center, under the hood. Just pull the relay, use a testlite, see how many hot circuits, two for each relay should be hot all the time. You need to have codes checked, see if it shows anything? The headlamp switch sends signal to bcm, bcm grounds the coil side of those relays, mentioned.

When you check fuses, also use a testlite and check for voltage on the fuse circuit. Even if the fuse is good, if there is no voltage on the circuit, the circuit is still dead.
