Thanks, pizzaguy. I really appreciate your advice. I did check with ignition set to ON. I will take a close look at fuse 4 this evening. The service manual seems to indicate that fuse 4 also controls rear directionals and taillights, and all of those are working properly. But it is an easy check, I will take a look anyway. Your info on bolt access is much appreciated, that was the thing that had me worried. I have a switch coming in from FCPEuro, if the fuse 4 check doesn't solve the problem I will take photos of the switch replacement and add them here.
