Cardone New Wiper Motor Design

Cardone’s Windshield Wiper Motor line focuses on replacing worn original units with a new motor design that improves durability where wiper systems commonly fail. The 85-3508 uses stronger gear material than original equipment to reduce premature wear, stripping, and breakage, while the motor is assembled with the correct lubricant amount for quieter operation and longer service life.

What This Wiper Motor Helps Solve

• Front wipers that stop mid-windshield
• Slow, weak, or inconsistent wiper movement
• Wiper motor gear wear, stripping, or breakage
• Poor parking alignment after motor replacement
• Noise caused by worn internal motor components

Installation Notes and Tips

Verify the vehicle uses a motor without a washer pump before installation. If the wipers do not park correctly and the vehicle does not use hidden wiper blades, check crank arm position on the motor shaft and reset the park position according to the service manual. If the system includes a moisture sensor or rain-sensing wiper control, confirm the related module and sensor are functioning before replacing the motor. If the washer pump is defective, some systems will not allow the motor to operate, so bench test both components before installation.

Quality Assurance

Cardone designs this new wiper motor using reverse-engineering experience from remanufacturing programs and applies load testing to confirm performance. The motor is built with upgraded gear material and controlled lubrication to support long-term operation in front wiper service.
