Replacing the car wiper linkage rod tutorial is: 1. Remove the wiper blade, open the hood, and unscrew the fixing screws on the cover plate; 2. Bend down the engine cover sealing strip, lift the cover, disconnect the spray pipe interface, and remove the cover plate; 3. Unscrew the screws under the cover plate and remove the inner plastic plate; 4. Disconnect the motor plug, unscrew the screws on both sides of the linkage rod, and then pull it out; 5. Reinsert the assembly into the rubber hole of the linkage rod, tighten the screws, plug in the motor connector, and restore it. The wiper linkage rod uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part.
I often help friends replace windshield wiper linkage rods, and the process is actually not complicated. First, disconnect the negative terminal of the car battery to avoid short-circuit risks and ensure safe operation. Next, use a wrench or specialized tool to remove the fixing nut on the wiper arm, being careful not to scratch the windshield. After removing the wiper arm, open the hood, locate the linkage rod assembly, and unscrew the connecting bolts to remove the old part. Then, install the new linkage rod, align the interfaces, and tighten the bolts with appropriate torque to prevent loosening. Once done, reinstall the wiper arm, ensuring the angle is correct, and test the wiper operation for smooth movement. Wear gloves during the process to protect your hands, and apply rust remover to lubricate any rusty parts. The whole job takes about half an hour. Regularly checking the wiper condition can prevent issues, save money, and provide practical knowledge while reducing trips to the repair shop.
