Good morning, KARENSKI916,

I would check the fuse first. I am adding a wiring diagram for you for the exterior lights. It shows there is a 20-amp fuse for this circuit. I have also added a diagram of you fuse box according to the info I have.

It doesn't give me a location for this panel except for by the instrument cluster but I believe it is under the steering column to the left on the firewall.

This article will help in checking the fuses using a test light:

I feel this is the best way to test because sometimes bad fuses look fine when pulled. Better to test them in place with a test light.
