It sure sounds like a bad ground somewhere. I just fixed a weird brake
light problem in my fiancee's Mazda 626 which I traced to a loose
ground wire on the rear tail light assembly.  Check for loose ground
wires on things like that, where you don't have a solid ground to the
chassis so an extra ground wire is run over to it.  If the ground
connection is bad, you end up completing the circuit through some
other convoluted path (like other lights, switches, the radio, etc.).
