To access the wiper/washer switch, one has to pull it towards the side of the car carrying the passenger, having to push in the pawls located at the upper and lower part of the case, after which one has to pull the switch out and unplug the electrical connection.

The combination switch: first unplug the electrical connection then to actually unmount the switch, there two clips that must be depressed-on the upper and the lower portion of the switch while it is pulled toward the driver's side. If applied, reinstatement goes in the opposite order to that of elimination.
