were the lights UP or DOWN?
did the lights move, if so which way
during my career, I had the rep of always providing the worse case for simplest of syptoms
IF a limit switch failed to shut the motor off, the current when the motor becomes "locked Rotor" is GREAT. I don't have real world experaince, but I would guess the current would burn a fuse....(So you might have some damage to your key switch)
Fuse 10 is actually off the ACC position on the Key, so be sure not in that position
the other item on F10 would be the AC/Heater blower, might check to see if it comes on with key off
Is it possible your wiring has been modified?
