LV ELECTRICAL SYSTEM 31 3. Lubricate (one drop) hinge joint area in each vehicle service to achieve proper arm pressure. 4. Check the wiper blades at least twice a year or when they seem less effective. Substances such as tree sap and some hot wax treatments used by commercial car washes reduce the effectiveness of wiper blades. 5. If the wiper blades do not wipe properly, clean both the windshield and wiper blades using undiluted windshield wiper solution or a mild detergent. Rinse thoroughly with clean water. To avoid damaging the blades, do not use fuel, kerosene, paint thinner, or other solvents. 6. When replacing wiper blade assemblies, always use specified parts or equivalents. To make replacing the wipers easy, turn the ignition to ACC, and then turn the wipers on. When the wiper reaches the vertical position, turn the ignition to lock.
