Another danged problem

Yesterday I parked Pumpkin on the drive slab parallel to the garage.  This is the best way to get it level for testing fluid levels, etc.  I checked the oil, brake fluid, power steering fluid, coolant, windshield washer fluid and battery water.  While parking Pumpkin, I had rolled down the driver's side window so I could see better.  So, when I finished checking things I rolled the window back up - or tried to.  It wouldn't go.  Pushed the button and nothing.  The passenger side didn't work either.  So, I went looking for a blown fuse.  Instead of a blown fuse, I found one that had nearly fallen out under the dash.  One of the previous owners (I can't believe the manufacturer did it) had jammed a wire in for the "jacks down" warning light on one end of the fuse.  For whatever reason, the wire decided to come loose at this time and partially pulled the fuse out with it.  I put the fuse back in and the windows work again, but now I have to find a better place to get 12 volts for the warning light.  At least this problem should not cost anything except time.
