Behind center of the dash is your lighting control module when the lights are inop you will have to check your input and output in the lighting control module. The white wire with a black stripe should have a ground input of 2 ohms or less with the parking lights on. Then the brown wire should be a battery voltage output with the parking lights on. Let me know what you find.
