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!

1997 960 now with a 1998 S90 trunk lid. initially worked fine, now has this bizarre problem
