Welcome to the forum.
I think you meant the parking lights rather than "tail lights." The Parking Lamps fuse protects the parking lamp circuits as well as the instrument illumination circuits (instrument cluster, various lighted switches, dials, knobs).
I guess it's easy enough to check the circuit boards inside the taillamp assembly. They tend to develop faults on your generation Malibu. Also, if a parking/illumination lamp that should be lit but isn't (not to forget the front parking lamps and side markers), it may indicate a wiring problem behind it. If not those, the culprit can be anywhere in the paths that power the lamps both interior and exterior. Sites of previous repairs are always suspect but it may take a substantial teardown and lots of luck and patience.
