rear left tail light not working,brake and signal light work fine.
Replace the bulb..
not a good answer, bulbs all replaced.
Didn't know that, then try moving the new bulb around in the socket to try and make a connection with the park lights on so you can see. Is this just the park light? Or is it the double filament bulb?
Check the battery terminals or battery cables they may be loose causing the issues , if not that then check the BCM. I replaced these both and my issues are gone
