For your 2003 Ford Explorer, since you have replaced the switch and the bulbs, I recommend you check your fuses and relays if you haven't already done so. You will want to check fuse 5 in your passenger compartment fuse panel and also relay 1. If this is not the issue, I recommend taking it to a mechanic to have them troubleshoot unless you are comfortable with testing wires using a circuit tester like # PTW2993 to check each wire from the switches to the bulbs and replace wires as needed.
