Global Parts 2311581 HVAC Blower Motor - Rear

Global Parts 2311581 HVAC Blower Motor

Global Parts 2311581 is an OE replacement HVAC blower motor assembly built for 12-volt vehicle electrical systems. It uses a metal housing, flange mounting, and a single-shaft design with a vented motor and cage wheel included to move air across the A/C evaporator and support cabin cooling and heat transfer.

The Global Parts Blower Motor line focuses on direct-fit HVAC service parts, and this assembly follows that approach with a plug connector, 1 spade terminal, and variable-speed operation. It is a practical replacement for vehicles such as Chevrolet Astro, GMC Safari, and Chevrolet P30 applications where the blower motor and wheel assembly are serviced together.
