The problem

Many Citroën C2 C3 C5 owners have experienced a problem with the heater blower not working properly.
Owners may experience an intermittent heater blower fan, on one or more of the speed settings, or the fan may not work all, or only on full power, or may be stuck on full power.

The cause can be a fault in the electronic control panel, the resistor pack, or the blower motor.
The most common cause however is:
A faulty Resistor Pack.
(otherwise known as the Heater Blower Resistor, Rheostat, or Blower Motor Resistor)
(Part No's F657165W/M / 6441L2 / 7701207718 / 7701048390 )
Note the green connector.

To access the resistor pack, it is usually located to the left of the base of the steering column, behind the trim, and retained with two 6mm hex screws.
Here's an example on a Citroën C5
Resistor Pack location for Citroen C5

To buy a new resistor pack from Citroen would cost in the region of £100, so it obviously makes sense to try and pin-point the source of the problem.

You may find that one or both of the green connectors are burnt out.
You can purchase them as a pair below.

The cause

If the blower only runs on the fastest selected speed
The fault must be in the electronic facia control panel, or the Resistor Pack.
Experience states that it will be the Resistor Pack at fault.

The solution

You could buy a new Resistor Pack from Citroen at £100 or so.
If it doesn't fix your problem, that is dead money.
Alternatively, you could get your own Resistor Pack repaired by our expert technicians, who will give you a satisfaction guarantee that lasts for 12 months.
