Ford Focus LT/LV 2007–2011 Manual A/C Blower Resistor 3M5H-18B647-AC

Replacement 4-pin blower motor resistor for Australian Ford Focus LT and LV vehicles fitted with manual heater and air-conditioning controls. A failed resistor can cause one or more cabin fan speeds to stop working, but the fuse, wiring, connector and blower motor should also be checked before replacement.

Australian vehicle fitment

• Ford Focus LT series, approximately 2007–2009.
• Ford Focus LV series, approximately 2009–2011.
• Manual heater and air-conditioning controls with a matching 4-pin connector only.

Important exclusions and checks

• Not suitable for automatic or dual-zone climate-control systems.
• Not suitable where the connector, mounting shape or existing part reference differs.
• This is the fan-speed resistor; it is not the blower motor, fan switch or climate-control panel.
• A stiff or high-current blower motor can damage a new resistor. Inspect the motor, cabin filter and connector for overheating before installation.
