Blower Switch Knob, Cab HVAC Control Replacement SKU: QT44163

This blower switch knob restores user control over cab airflow by giving you a physical interface to adjust fan speed. A broken or missing knob prevents satisfying control of heating/ventilation settings.

Made for everyday use in cab environments, its durable material resists cracking, wear, and exposure to heat and sun. It fits into standard blower control assemblies with minimal fuss.

• Replacement knob for cab blower switch in HVAC systems
