Ensure the Wiper Motor Gets Power:
1. Check the fuse box for a burnt fuse. Replace it if necessary.
2. Inspect the wiring connections to the motor. Make sure they are clean and tightly fitted. Clean any corrosion with sandpaper and reconnect firmly.
3. Check for voltage with a multimeter. If there's no power to the motor, consult a professional electrician for further diagnosis of the electrical system.
Inspect and Replace the Wiper Blades:
1. Check if the wiper blades are damaged or worn-out. Cracked, warped, or brittle wiper blades can prevent proper movement. Replace worn blades with new ones of the correct size for your vehicle.
Look for Mechanical Obstructions:
1. Check the linkage arms and pivot points for any obstructions. Look for any misalignment or binding, and make necessary adjustments to allow for free movement.
2. Clear away debris or ice buildup from the linkage or wiper transmission mechanisms that could be preventing movement.
Lubricate Linkage and Motor:
1. Apply a small amount of silicone-based lubricant to moving parts like pivot points, linkage joints, and around the wiper motor shaft. This reduces friction and improves wiper blade movement.
Verify the Linkage Mechanism:
1. Check if the linkage mechanism is intact. If any parts are damaged or disconnected, replace them or reconnect properly.
2. Inspect the wiper transmission gears for any wear or damage. If they're damaged, you may need to replace the entire transmission.
Test the System:
1. After performing the above steps, turn on the wipers and check if they move smoothly and in the right direction.
Note: If the issue persists or you encounter any electrical complications, it's advisable to consult a qualified mechanic or auto electrician to handle the diagnosis and repair to ensure accurate results and avoid potential safety risks.
