Issue - License Plate Lights

Due to the high temperature of the bulb, after a few years of use the plastic becomes fragile and the rubber washer becomes unreliable letting moisture through eventually causing corrosion of the bulb contacts or worse the wiring resulting in eventual failure.
- License Plate Lights may not work due to a blown supply fuse or a wiring fault.

Summary:
This is for problems where your license plate bulbs/lamps or just one are good but not turning on. Along with having the license plate warning light on the dash.
One snag you will run in to when diagnosing is that no power will be sent to the plate lamps unless the trunk is closed. I'm sure there is a way around this, I locked the latch and grounded it but that didn't work. Anyways with some of the panels you have to take off to get the lamp sockets out you will have holes to run your test leads through to pin the wire in different areas.
