alternately closes the wiper park switch sense circuit to ground or to battery current, depending upon the position of the wipers on the glass. This feature
allows the motor to complete its current wipe cycle after the wiper system has been turned OFF, and to park the wiper blades in the lowest portion of the
wipe pattern. The automatic resetting circuit breaker protects the motor from overloads.
The wiper motor crank arm, the two wiper linkage members and the two wiper pivots mechanically convert the rotary output of the wiper motor to the
back and forth wiping motion of the wiper arms and blades on the glass.
The hard wired inputs and outputs of the front wiper motor may be diagnosed using conventional diagnostic tools and procedures. Refer to the
appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the front wiper motor or the
electronic controls or communication between other modules and devices that provide some features of the front wiper and washer system. The most
reliable, efficient, and accurate means to diagnose the front wiper motor or the electronic controls and communication related to front wiper motor
operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
