Any Advice? OK, I'll take a *.W.A.G. (Silly Wild A$$ Guess). If you're really, Really sure that ALL the fuses are OK, then I would check the wires at the trunk release "thingy" and possibly use a VOM or circuit tester to see if any current is getting to that realease mechanism. It sounds like the window motors(regulators?) are really tired or dead and might need to be replaced. And with the right front door not unlocking (and the others work fine), it could be a loose connection, or the mechanism (bumper kit?) might need to be replaced. Sorry I can't help you with the "weird orange fuse".
