Default 603 S2 Windscreen wiper difficult to turn to operate...

Hi all -

I don't know anything about this specific switch, but doubt it was
overly stiff when new. Is there any access to the shaft behind the
plastic portion? I'd try shooting tuner cleaner/contact cleaner down
the shaft and rotating back & forth as much as feasible. WD-40 may
also work, but I've had better luck with other types of contact
cleaners. Best yet is "Rail-Zip", which hobbyists use to clean the
tracks on their layouts. Inexpensive and never seems to not improve
electrical contacts.
