Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Wiper/Washer Systems: Testing: 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 the cause and repair as necessary. Always check that the battery is charged and 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 the fluid hose is disconnected.
