My name is ***** ***** I will assist you with your concerns.
Check fuse F19 in the glove compartment. Fuse 1 is the far right and count to the left. That is the marker/running lights fuse.
If that fuse is good, then the issues will be in the relay or the switch.
I will post a picture of the location for the relay below.
Here is the wiring diagram for the vehicle, if needed.
