Do the contour water pumps have valves that will leak when they're going bad? Dunno, this is my second car and my old one (92 Mazda Protege, pump died at 198k miles) had a valve that leaked coolant as it was going bad to let you know you needed to replace it. I'm not losing any coolant.
When I replaced the fuse I turned the dimmer knob all the way both ways (just in case I had it wrong

) to check that.. no effects
