Detailed Product Information

Global Parts 1711344 is an HVAC blower control switch used in climate control systems that rely on electrical feedback to manage A/C operation and blower function. On modern vehicles, the ECM can control the A/C system through this switch input; on earlier vehicles, the switch can directly shut off compressor operation to help prevent compressor damage. This makes it a practical replacement for worn or intermittent blower selector switches in GM cars, trucks, vans, and SUVs.
