Been there, done that, and the problem has been posted before. The switch module is not easily dismantled and cleaning the switches with electronic contact cleaner really doesn't work. Further, the individual switches are not replaceable. The entire module will have to be replaced. It is not cheap. The only good news is...It is easely replaced and I suggest you purchase the module and install it yourself. It will take about 90 minutes if you have every removed the centre column before for replacing bulbs for example. The modules simply plugs into a harness and snaps into the console. Remove the old and replace in opposite order. Good Luck.
