Peugeot 406 Heater Motor Replacement Parts

The Peugeot 406 ran from 1995 to 2004, with a facelift introduced in 1999, and the heater motor sits behind the dashboard in the heater box assembly on all variants. Parts from the pre-facelift (1995–1999) and post-facelift (1999–2004) cars may differ in connector design or housing shape, so crossing that 1999 boundary is something you should confirm with the breaker against your registration before buying. Within either generation, motors are generally consistent regardless of engine fitted.

The heater motor is part of the cabin heating system and sits in the same position across the 406 body styles — saloon, estate, and coupe. Body style does not typically affect fitment for this part, so a motor pulled from any 406 of the same generation should be a candidate. Confirm the part number or year against your registration with the breaker to be sure, as the coupe in particular may have minor differences.

No — the heater motor is independent of the engine, so it makes no difference whether your 406 has a petrol or diesel engine, or what capacity it is. All 406 variants were fitted with a cabin heater blower motor as standard, so you are not restricted to parts from the same engine variant. Focus on the model year matching your generation rather than engine specification.

Trim level — whether your car is an LX, GLX, SRi, or Executive — does not affect heater motor fitment; it is the same unit across the range for a given generation. You may find that higher-spec cars had air conditioning, which sits alongside but separate from the heater blower motor, so the motor itself remains the same part. Confirm the year of the donor car with the breaker rather than worrying about trim.

This crosses the 1999 facelift boundary, which is where Peugeot updated several components on the 406, and it is not certain whether the heater motor changed at that point. It is possible the unit is compatible, but you should confirm this directly with the breaker, quoting both registration numbers, before purchasing. Do not assume interchangeability across that 1999 model year divide without checking.

Give the breaker your full registration number so they can verify the exact specification of your 406 against the donor vehicle. It is also worth asking whether the motor is from a pre- or post-1999 facelift car, as that is the most significant production boundary on the 406. If possible, compare part numbers between your original unit and the one being offered before committing.
