Detailed Description

Cardone 40-166 is a remanufactured windshield wiper motor for front applications on select 1974-1975 Buick, Cadillac, Oldsmobile, and Pontiac models. It is listed for 1974-1975 Buick LeSabre, Regal, and Riviera; 1974-1975 Cadillac DeVille, Eldorado, Fleetwood, and Commercial Chassis; 1974-1975 Oldsmobile 98, Custom Cruiser, Delta 88, and Toronado; plus 1975 Pontiac Bonneville and Catalina. Fitment notes include intermittent wipers, one green wire from under relay, and washer pump excluded where specified.

This part cross-references Oldsmobile and Pontiac 9651058 for the same application. Use Cardone 40-166 when replacing a front windshield wiper motor on these GM platforms and you need an OE-style remanufactured unit that matches the original mounting and terminal style.

What It Helps Fix

• Inoperative front windshield wipers
• Slow or inconsistent wiper sweep
• Wipers stopping in the middle of the windshield
• Poor parking position after motor replacement
• Intermittent wiper operation problems on listed GM vehicles

Installation Notes and Tips

Verify the vehicle uses the listed intermittent-wiper configuration before ordering. This motor uses a grommet mount, blade terminals, and does not include a washer pump. If the wipers do not park correctly, check crank arm position on the motor shaft and follow the vehicle-specific hidden park reset procedure when applicable. If the motor does not operate after installation, bench test the wiper motor and washer pump, since a defective washer pump can prevent operation on some systems.

Quality Assurance

Each Cardone remanufactured wiper motor is re-engineered and tested to match OE performance. Main components are checked against original standards, and the final unit is function-tested on the vehicle. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
