• Faster cabin air exchange and restored blower speed range.
• Quieter operation reduces HVAC noise at higher fan settings.
• More efficient airflow improves heating and cooling responsiveness.
• Protective features reduce the risk of premature motor failure.

Who is this for: Drivers of the listed Buick, Chevrolet and Pontiac models who are experiencing weak airflow, unusual blower noise, or intermittent fan speeds and who need a front-position blower replacement.
