Mine didn't work when I got it. I took the light itself off the ceiling and cleaned it before I noticed the PO had actually removed the switches off the doorframes. <img src="/forums/images/graemlins/confused.gif" alt="" />
I ended up getting new ones from a Mitsu dealer. The driver's door switch is a "2-wire" and the other 3 are single wire switches. You can modify a 2-wire to make a single wire one.
