Hello kind folks. My son is driving my 2010 Mazda 3. He got pulled over for no license plate lights. He replaced the bulbs at Auto Zone, but the new ones don't work either. I checked many fuses for a busted fuse as the manual didn't seem to specify the exact fuse for this issue - but no busted fuse was found. What could be going on here? This car has never given us issues. It has always been a champ.
