Description
This is a genuine Mazda heater blower resistor for Mazda 323, 626, Premacy and MPV models. The primary OEM number is HM636040B, with alternate reference KJ151GE6R. It is an original HVAC electrical component used to control blower motor speed within the cabin heating and ventilation system.
By regulating electrical current to the interior blower motor, this resistor helps the fan operate at different speed settings selected from the dashboard controls. Proper function is essential for stable airflow through the heater and ventilation system, supporting cabin comfort, windscreen demisting and normal air distribution.
Common signs of a faulty unit include the blower fan working only on one speed, certain fan settings not responding, intermittent cabin airflow, or the fan stopping completely while other heater controls still appear normal. In some cases, overheating at the resistor or connector area can also point to failure in this part.
This is a used original part, removed from a vehicle and tested before sale. Match HM636040B and KJ151GE6R with your existing unit before ordering. Professional installation is recommended, and related wiring or connectors should be inspected during fitting.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
