(located on the right side of the steering column) controls
the operation of the rear wiper/washer function.

position for rear wiper operation.
Rotate the switch upward past the first detent
to activate the rear washer. The washer pump

to the “Park” position. When the vehicle is restarted, the
wiper will resume function at whichever position the
