700110 Front AC Heater Blower Motor Fan Fit for Buick LeSabre - Quiet

In this review of the 700110 Front AC Heater Blower Motor Fan, the bottom line is simple: this is a direct-fit replacement for owners of several General Motors sedans who need reliable cabin airflow. It is best for DIYers and professional installers seeking an OEM-style unit that matches the listed fitments and brings stronger blowing capacity with a quieter, longer-lasting motor. The reviewer found the unit to be well built from ABS and metal, with improved motor components that reduce interference and extend service life.

Key Features

• Direct fitment: Designed to fit Buick LeSabre 2002-2005, Cadillac DeVille 2002 (2nd design) and 2003-2005, Seville 2003-2004, Oldsmobile Aurora 2002-2003, and Pontiac Bonneville 2002-2005 for straightforward replacement without modification.
• OEM interchange: Matches OEM numbers 700110 and 89018521 so it installs in place of common factory blower motors.
• Durable construction: Made from high-quality ABS material and metal for improved resistance to wear compared with cheaper plastic components.
• Upgraded motor: Uses a premium motor designed for low interference and quieter operation while aiming for a longer lifespan.
• Strong airflow: Dual function design pushes cold air from the evaporator or warm air from the heater core quickly into the cabin for effective ventilation and heating.

Who It's For

This blower motor is ideal for owners of the listed Buick, Cadillac, Oldsmobile, and Pontiac models who want a near-OEM replacement that restores cabin airflow and HVAC performance. It suits mechanics and capable DIYers who prefer replacing the blower rather than troubleshooting multiple HVAC components.

It is less appropriate for vehicles outside the stated fitments or for owners seeking an exact factory-branded part number from the original equipment manufacturer; those buyers should verify fitment carefully or consult a dealer for factory-specific replacements.

Pros & Cons

Pros

• Direct-fit for multiple GM models, which simplifies installation.
• Construction uses ABS and metal for durability under cabin conditions.
