The problem

Many Renault Laguna II 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 Resistor, Rheostat, or Blower Motor Resistor)
There are two possible types, depending on whether you have electronic climate control or not.

Resistor Pack for Renault Laguna 2

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.

The cause

If the blower only runs on the fastest selected speed or runs at high on all settings.
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.
A faulty resistor pack can also cause no blower action.

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.

Whichever option you choose, you need to identify which version of resistor pack you have fitted.

Identification and location

You can easily identify which type of resistor pack you should have fitted, by the type of heater controls on your centre console.
The resistor pack is located next to the heater fan in the passenger footwell, covered by some soundproofing.
The two types of resistor pack are very different, so it should be a simple matter to identify which you need from that.
