Hi taylorr01234,

Thank you for the donation.

The headlight relay is located at right front corner of engine compartment and if the relay is faulty, all those light you indicated would not work. Sorry I could not find any diagrams to show you.

Have you checked the Head fuse ( 30 A) in main fuse block at left side of engine compartment?

At the light switch, with lights turned on, use a test lamp to ground the White/Red wire. If lights turn on, the switch is bad.

If lights does not turn on, the headlight relay is bad.

Did you try swapping the relay?

To remove the switch you need to remove the steering wheel and column covers.

For testing you can use the wire harness going to the fuse box.

If equipped with airbags, extra precautions has to be taken while removing and installing the steeering wheel.
