I have a 1989 Sidekick.  My headlight switch works fine for parking lights and high beam, but does not work for my dim lights.  My parking lights and dash lights work but my low beams will not burn.  It did this about a year ago and I shoot some contact cleaner into the switch and low beams worked.  This time it didn't work.  Has anyone had the same problem and is there any fixes besides getting a new switch?  Bet a new switch is pricey.  Thanks,  John
