From Taurus Car Club Maintenance and Modification Wiki

Does your wiper/washer not work? Or do they work erratically? Maybe your high beams don't turn on. Or the highbeams only work with a certain combination of the wipers being on. Well, cleaning the multi-function switch may help! It gets pretty dirty in there from age so it's best to clean the gunk out with some electrical contact cleaner or rubbing (isopropyl) alcohol and a Q-tip.
