Prise up the drivers door switches, then unplug the two plugs, there on the unit you will fine four small terex screws
Undo all four and the switch assembly will come apart on the base section you fine four round pads, carefully clean these
Pads with alcohol or some other good contact cleaner, these pads for some reason get clogged with dust and grease,reassemble all should be good
