The troubleshooting methods for windshield wipers are: 1. Check the fuse to ensure there is no open circuit, and the wiring should not be loose; 2. Inspect the power and ground wires of the wiper motor and switch to ensure good contact and no open circuit; 3. Verify that each terminal of the switch can properly connect in the corresponding gear; 4. Check the motor and mechanical connections. The usage method of windshield wipers is: 1. Locate the wiper control lever on the lower left side of the steering wheel; 2. Push the wiper lever up one gear to start the wipers; 3. To turn off the wipers, push the lever down to the 'off' position. The replacement method for windshield wipers is: 1. Lift the wiper upright; 2. Press the clip below to remove the wiper blade; 3. Take off the wiper; 4. Lift the front end of the middle clip; 5. Insert the wiper into the middle clip, pull it tight by hand until you hear a click sound, indicating the replacement is complete.
I've been driving for over twenty years, and wiper problems are all too common. First, check if the rubber blade is aged—feel it with your hand for cracks or deformities. Turn on the wipers and listen for a humming sound from the motor. If there's no sound, it's likely a blown fuse; lift the cover under the steering wheel on the driver's side to check. If the blade squeaks or skips while wiping, replace it immediately—a roadside shop can do it for around thirty bucks. Before the rainy season, sanding the old blade can be a quick fix, but don't rely on it often. Remember, never operate the wipers on dry glass, as sand can scratch it. If all else fails, buy a can of rain repellent and spray it on the windshield—water beads will roll off on their own.
Last time I learned how to repair wipers from my master, the sequence is crucial. First step is to remove the wiper blade and check if the rubber strip is cracked, as this is the easiest part to replace. Second step is to test the washer fluid function; if the nozzle is clogged, use a needle to clear it. Third step is to measure the motor voltage by locating the fuse box in the engine compartment and using a test pen to check for blown fuses. Fourth step is to listen for any abnormal friction sounds from the wiper linkage, which might indicate a lack of lubricant. Motors rarely fail but are expensive to repair, so our workshop always keeps refurbished motors in stock. Lastly, a reminder: car washes often offer free windshield washer fluid refills—avoid using tap water to prevent scaling and clogging the pipes.
