I have removed the window motor from the right front door. Using a continuity meter between the two wire leads, there is an obvious open circuit. The motor winding, commutator, and brushes are fine; they show continuity. There is a black, rectangular object inside the motor assembly, in electrical series with an inductor. The black box is less than an inch long, and says "9 017" on it. This black box fails to show any continuity between its two terminals. I think it's a blown fuse.
Can anyone concur that this is a fuse? Is there a chance I can buy such a fuse? Any tips on where to buy? I'd rather not buy the entire motor, as that seems unnecessarily expensive. If it's a blown fuse, it blew because someone I know was messing with the mechanism. I'm confident there is no major problem, here.
Any idea what the amperage of such a motor fuse would be? I might need to improvise.
Thanks, John
