HVAC Blower Motor Switch for Mazda 3

Standard Ignition HS-546 is a 12-volt HVAC blower motor switch built with a square plastic housing, a plug-in attachment method, and a 6-blade male terminal layout. It uses a 4-position toggle actuation style and a single female square connector for direct replacement service on select Mazda 3 applications.

Key Features

  • Part number: HS-546
  • HVAC blower motor switch for climate control fan speed selection
  • 4 switch positions with toggle actuation
  • 12-volt electrical design
  • Plug-in attachment method with 1 female square connector
  • 6 male blade terminals
  • Black and white finish with plastic housing
  • No bulb, wiring harness, or mounting bracket included

Application Details

Compatible with 2012-2013 Mazda 3 models. This HS-546 blower motor switch is listed for N/A position and is not compatible with automatic AC systems. For Mazda 3 HVAC blower motor switch replacement, confirm the connector shape, terminal count, and control style before installation. This part cross-references BGV561200 for the same application.

Common Problems It Can Help Solve

  • Blower fan speeds that do not respond correctly
  • Intermittent HVAC fan operation
  • Worn or broken fan speed selector contacts
  • Loose or damaged switch connector terminals
  • Loss of manual blower control in the cabin HVAC panel

Installation Notes

Verify the vehicle uses a manual HVAC system before ordering, since this part is not compatible with automatic AC systems on the listed Mazda 3 applications. Match the 1-connector, 6-terminal configuration and square switch shape to the original unit. Plug-in installation simplifies replacement, but the existing connector and surrounding trim should be inspected for heat damage or terminal wear before the new switch is installed.

Quality Assurance

Standard Ignition HS-546 is built as an OE-style HVAC control replacement for the listed application and follows the specified connector, terminal, and actuation requirements for proper fitment.
