stick ur fingers behind and turn the plastic that holds the bulbs… I had to replace them on the road with no tools… Now my problem is?" New bulbs, good fuse, and still no license plate lights!!
check you connection points for corrosion and that they are on bare metal and not loose as for the screws being tough to get out just use a screw extractor i had the same problem used a screw extractor the screws came out with no plastic breakage and easy as pie.
