Wiper System, Windshield

The windshield wiper system consists of a wiper control module, an electric wiper motor, a washer system, and wiper/washer switch integral with the turn signal lever (multi-function switch (13K359)).

Off/Low/High Speed

The permanent magnet three-brush F windshield wiper motor (17504) allows selection of either low or high speed. When the wiper switch is in the LOW position, the common brush (Y/R) and low speed brush (DB/O) are used. When the switch is in the HIGH position, current bypasses part of the armature winding to the high speed brush (W), causing the windshield wiper motor to run faster. When the switch is moved to the OFF position, the windshield wiper motor will continue to run at low speed until the wipers park.

Interval

NOTE: When using interval wipe, the first wipe may not occur until after a pause of up to 12 seconds.

When the wiper switch is in the interval position, it is normal to hear a slight click at the beginning of each wipe/pause cycle. The wipers will make single sweeps separated by a pause. The control knob on the end of the switch sets the length of the pause from approximately 1-12 seconds each.
