He said he replaced the switch. Get a voltmeter, test the switch you replaced. You dont need a wiring diagram, theres only two wires at the switch like cruzalekz said.
Check your wires at the bulbs, make sure theres no rips in the insulation and that theres no oxidation in the sockets where the bulb goes. Use contact cleaner and a flathead to clean the contacts.
Also, make sure you got the correct bulbs:
