2 Answers
Replacing the windshield wiper linkage rod can be done by following these steps: 1. Remove the wiper blades, open the hood, and unscrew the fixing bolts on the cover plate; 2. Pull off the hood seal strip, lift the hood, disconnect the washer hose connector, and remove the cover plate; 3. Unscrew the bolts under the cover plate and take off the inner plastic panel; 4. Disconnect the motor plug, unscrew the bolts on both sides of the linkage rod, and then pull it out; 5. Remove the motor from the old linkage rod, install it onto the new linkage rod, reinsert the assembly into the rubber hole of the linkage rod, tighten the screws, reconnect the motor plug, and restore the seal strip and cover plate.
As an old car enthusiast, I've replaced the wiper linkage several times, especially on those older vehicles where the rods tend to rust and break, causing the wipers to jerk. Before replacement, make sure to prepare the tools: a standard socket wrench set, a Phillips screwdriver, and protective gloves for better grip and safety. First, park the car securely, pop the hood, and disconnect the negative battery terminal to avoid electrical hazards. Remove the wiper arm's retaining nut, carefully loosening it with the wrench—don't force it to prevent windshield damage. Then locate the linkage assembly, usually beneath the wiper motor, possibly secured with clips or screws; unscrew and remove the old rod. Align and install the new part exactly as the old one, ensuring the holes match before tightening. Reattach the wiper arm and test for smooth operation—if it squeaks, apply silicone grease to lubricate the joints. The whole process takes about 30 minutes. Beginners should refer to the vehicle manual for safer DIY steps—never rush or skip safety checks to save time.
