Introduction

Wiper motors play a crucial role in ensuring clear visibility during adverse weather conditions. Ongaro wiper motors are renowned for their reliability and efficiency. However, periodic adjustment is essential to maintain optimal performance and ensure long-term functionality. This comprehensive guide will provide step-by-step instructions on how to adjust an Ongaro wiper motor.

Understanding Wiper Motor Adjustment

Wiper motors are typically adjusted for two main purposes:

Park Position Adjustment: This adjusts the resting position of the wiper blades when the wiper switch is turned off.

Wipe Interval Adjustment: This adjusts the time delay between successive sweeps of the wiper blades.

Materials Required

Phillips screwdriver

Flat-blade screwdriver

Torque wrench (optional)

Owner's manual for the specific vehicle

Safety Precautions

Disconnect the battery before performing any electrical work.

Wear safety gloves and eye protection when handling tools.

Do not attempt to adjust the wiper motor while the vehicle is running.

Step-by-Step Instructions

Park Position Adjustment

1. Locate the Park Position Adjustment Bolt: Refer to the owner's manual to identify the location of the park position adjustment bolt. It is typically located on the wiper motor itself or on the linkage connecting the motor to the wiper blades.

2. Loosen the Locknut: Use a Phillips screwdriver to loosen the locknut located next to the adjustment bolt.

3. Adjust the Bolt: Use a flat-blade screwdriver or a torque wrench to turn the adjustment bolt clockwise or counterclockwise in small increments.

4. Test the Position: Turn the ignition switch to the "On" position without starting the engine. Activate the wiper switch and observe the resting position of the wiper blades.

5. Retighten the Locknut: Once the desired park position is achieved, retighten the locknut to secure the adjustment.

Wipe Interval Adjustment

1. Locate the Wipe Interval Adjustment Screw: Refer to the owner's manual to identify the location of the wipe interval adjustment screw. It is typically located on the wiper motor or in the wiper control module.

2. Turn the Screw: Use a Phillips screwdriver to turn the adjustment screw clockwise to increase the delay between sweeps or counterclockwise to decrease the delay.

3. Test the Interval: Activate the wiper switch and observe the time delay between successive sweeps of the wiper blades.

4. Adjust as Needed: Make small adjustments to the screw until the desired wipe interval is achieved.

Additional Tips

Before making any adjustments, ensure that the wiper linkage is free of any obstructions or corrosion.

If the wiper blades are chattering or skipping, it may indicate incorrect park position or wipe interval adjustment.

If the wiper motor is not functioning properly, there may be an electrical or mechanical issue that requires professional attention.

Regular maintenance and adjustment of the wiper motor will extend its lifespan and ensure optimal performance.

Conclusion

By following these step-by-step instructions, you can effectively adjust an Ongaro wiper motor and ensure clear visibility during all weather conditions. Remember to approach the adjustment process with caution and refer to the owner's manual for specific vehicle requirements. With proper maintenance and care, your wiper motor will provide years of reliable service.
