Hi and thanks for using 2CarPros.
I am not sure why, but I do not have a layout of the fuse box or relay box, so I had to look through schematics. Under the hood, passenger side rear, is the relay box. First, for the low beam, check and confirm fuses 76 and 86. If they are good, confirm fuses 72 and 74 are good.

Next, if the fuses are good, switch the low relay with another one in the box that has the same part number to see if that is the problem. If there is not one with the same part number. Here is a link that describes how to check a relay:

If everything checks good, make sure the bulbs are good.
Let me know if this helps.
Take care,
