Hey Chris, welcome to the tribe....While you have the switches out,  
you can drill a tiny(size of a spray can red tube) hole about center  
of both sides(just thru the plastic).  Get a can of electrical  
contact cleaner and spray and switch the switch back and  
forth....I've "fixed" many switches this way, and if I'm in there,  
will do it as preventitive maintanance to any vehicle....I fixed 3  
out of 4(drivers) in 1 car.  The both rear windows(and I believe the  
rear cig lighter) are disabled by the red switch, so if you have no  
rear cig lighter, then I'd look at the red switch/bad wire in the  
rubber boot in the door.  If that's the only thing wrong with the  
car, be happy.....Tom
