I noticed an interesting feature of my 1992 900s tonight: the random and unbidden operation of the dome light. It seems to be turning itself on and off while I drive, seemingly at random. The switch is, as usual, in positing "1" (i.e. on when door opens). Any thoughts as to where I should look in tracking this down? Could it be corrosion in the switch itself, or should I be looking elsewhere?
Thanks, John
