Blower Switch, Multi-Speed Cab Heater Control SKU: QT43163

This blower switch restores multi-speed control to your cab heater/ventilation system, letting you regulate airflow even in extreme conditions. Replacing a failed switch ensures you maintain comfort, defrosting ability, and safe visibility in daily use.

Constructed with durable internal contacts, it tolerates repeated use and the higher amperage demands of a cab blower motor. The sealed housing guards against dust and moisture that often shorten switch life.

• Multi-speed fan control for cab blower and HVAC systems
• Heavy-duty internal contacts to withstand repeated switching
• Sealed switch body to resist dust and moisture intrusion
• Designed to mount in standard dash cutouts; no major modification needed

Installation Tip: Disconnect the negative battery terminal first. Remove the old switch by backing off the retaining nut behind the dash. Wire the replacement exactly as was before (take a photo beforehand), then secure with the nut and test blower modes before reassembling trim.

A dependable replacement to get your cab airflow control working again under field conditions.
