The lite blue wire is voltage for lower stop lamps, Check for voltage with brakes applied. If no voltage, check vehicle stop fuse. Not only check the fuse, check for voltage on the fuse circuit, You can use a testlite.

Note the diagram for the stop and tag lites. For the tag lites, top wire is voltage, black wire is ground. There could be a problem with voltage wiring circuit? The applicable fuses are under the rear seat.
