The problem

   Renault Scenic 2 electronic aircon controls             Renault Scenic 2 heater controls (no aircon)
Controls with climate control (left), and without climate control (right)
Many Megane/Scenic Mk 2 owners have experienced a problem with the heater blower not working properly.
Here we deal with those vehicles with electronic aircon (climate control), as pictured above left.
Otherwise, see Renault Scenic 2 without climate control or Renault Megane 2 without climate control

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 Resistor, Heater Blower Resistor, Rheostat, or Blower Motor Resistor)
(Part No's 6441L2 / 7701207718 / 7701048390 )
Resistor Pack for Renault Megane 2 Scenic 2Green plugs for 6441L2

To buy a new resistor pack from Renault 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 runs on some selected speeds, but not others:
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.

If the blower is dead
The fault could also be in the blower motor, or the fuse.
However, usually it will still be the Resistor Pack at fault.

Underlying problems
When the Resistor Pack fails, it can simply be because it has failed, but equally, it can be because of an underlying fault, such as a blocked air inlet (check for leaves) or a blocked filter.
Also, if the blower motor is seized, or partially seized, the additional load may well lead to failure of the Resistor Pack.

The solution

You could buy a new Resistor Pack from Renault, at £100 or so.
If it doesn't fix your problem, that is dead money.
Alternatively, you can get your own Resistor Pack repaired by our expert technicians, who will give you a 12 month satisfaction guarantee.
You also don't have to worry about ensuring compatibility, as you get your own control back.

Also ensure that you check for any underlying cause of failure, such as a blocked filter or faulty fan motor, and ensure this is rectified before refitting the Resistor Pack.
