Sounds possibly like the switch itself is bad. The switch is a part called the combination or "combi" switch. It controls the wipers, turn signals, and high beam/low beam. It is, in effect, the "stalk", the switch is inside the steering column.
To test the theory I'd find the connector for the wiper motor and try jumping it to battery power and see if it runs normally.
On the lubing process you did, did you lube the shiny shaft that makes the eccentric sweep of the wiper blade (the rod that moves up and down as the wiper sweeps)? I've heard regular transmission fluid is good for lubing the shaft.
