Hello all, I am new to the forum game.. anyway, I had to replace my trunk lid with that from a S90, which is pretty much if not the same exact car. anyways, for some reason my left turn signal doesn't work (even with the hazards) and the right tail light doesn't illuminate. all the other lights (i.e. the lights on the trunk lid, right turn signal, and left taillight) all work normally. Any thoughts on why this would happen? they all worked a few days ago when I tested the lights after changing the trunk lid, but now i have this problem. Thanks for your time and help!

 

It sounds like something might just be loose to me. Have you double checked all of the connections? I worked at an auto parts store for a long time and I've seen plenty of times where the mechanism in the wiring that connects to the bulb is loose. A little prying with a flat head and you can usually bend the piece back out to make a good connection. Let us know what you find.
