Could be several things but I would start by cleaning the bulb socket with emery cloth and applying a light coat of dielectric grease to the bulb contacts. There is a Molex connector behind the driver's side rear quarter panel that links the front harness with the hatch. That connector is prone to corrosion due to moisture, I would separate the connector, clean, and apply dielectric grease to the contacts. You may also need to pre-tension the individual sockets by compressing the metal female receiver slightly with an awl or other pointy thing.

I would agree....my connectors were so corroded when I pulled them apart they just fell apart so I just wired in new connectors on both sides!!!
