The high beams on the car work, but the low beans will not come on. Bulb are new, so what can I do to find the problem?

Welcome to 2CarPros.

These vehicle have separate fuses for high and low beam. Let's start with checking the low beam fuse.

The fuse is under the hood in the power distribution box. I have attached three pictures below. First is an overall picture of the box. The second is a close up of the fuses you need to check, and the last one is a legend identifying which fuses are for the lights.

The ones you are most interested in are the DRL 1 and DRL 2 fuses. Both are 15 amp and if bad, must be replaced with a 15 amp fuse.
