1 WINDSHIELD WIPER AND WASHER CIRCUIT DIAGNOSTIC PROCEDURES
IMPORTANT: Do not disconnect electrical connectors while the engine is running. Damage to Monitor
Controller or other components may result. Disconnect connectors only when instructed during a test or
check.
NOTE: If windshield wiper does not operate, first check the latch on the upper right corner of the windshield. The
windshield must be all the way down and the right latch must be secured to contact the windshield wiper enable
switch, which allows the wiper to operate.
Before troubleshooting the circuits, clean all terminals in the monitor controller and harness connectors using a
non-conductive lubricating contact cleaner, then try the circuit operation again before proceeding. TY16324 Contact
Cleaner can be used.
