Take a test light or volt meter and check for voltage at the fuses with the head light switch on. To at least see if you switch is working. Inside the switch the current is separate for the head lights and running lights. So you can still have head lights but not running lights if the switch is bad. The only things that should common to all the running lights are the switch and fuses, and of course the wires between the switch and fuse box.
Have also seen fuses "look" good, but won't pass current. It is best to check with a test light or meter.
Just looked at a few schematics. The running lights are fused before the switch. It would make sense to pull the headlight switch. Power in for the running lights should orange. Power in for the headlights is red. Power out for the headlights is yellow. The power color out for the running lights was not determined by 3 different schematics except that it supposed to be terminal L. So if switch is off you should have voltage on the orange and red wires. If not check the "TAIL" fuse or wiring between it and the switch. Should only have voltage on the yellow wire with the switch all the way on. If you don't get voltage on the other wires with the switch on the first setting, most likely bad switch. If you do get power out then you have an issue in the wiring after the switch.
