Long story short I finally got into my trunk the replacement key I got didn't work on the trunk. Anyway my inner tail light hadn't been working since I started driving it again but the outer one and break light did. Replaced the inner one and now the outer one only lights up when I break. Tried a light from my 05 s type r and that doesn't do anything, took out the inner light again, Checked the fuse and replaced it just in case and nothing changed. Any suggestions?
BTW it's a 2001 3.0

 

Please see these two threads. Seemingly unrelated fuses were blown and caused strange issues with various lights:

Also, check the spare tire well for water. The trunk seal is prone to leakage and lets water collect, which causes trouble with the various electronic modules back there..
