With the early style top mount wipers the grease gets hard over time. Pull the assy off and take it apart. Easy to do. There is a gear to grease and the shaft drive. I use white lith spray on the drive and regular grease on the gear. Make a big difference. I would not use grease on switches. Pull them out of the dash and clean the piss out of them with ele parts cleaner. let them dry then use a little dry graphite spray on the moving part.
