Wiper/Washer Systems: Testing: Front: Notes

Before performing any specific tests on a faulty wiper/washer system, check that the following fuses are okay: A 30-amp maxifuse is located in underhood junction block. A 25-amp mini fuse is located in the instrument panel fuse block. If either fuse is blown, determine cause and repair as necessary. Always check that battery is charged, terminals are clean and connected properly. Check that wiring connectors are securely connected and not corroded or broken.

Slow or jerky wipers, or wipers that stop and restart after several minutes are usually caused by low or intermittent battery power or too much friction between the wiper blades and the windshield. If washer fluid does not appear when WASH is activated, the washer fluid reservoir is empty or fluid hose is disconnected.
