The problem

Many Clio Mk II owners have experienced a problem with the heater blower not working properly.
Here we deal with those vehicles with climate control (digital aircon).
Vehicles affected include the Renault Thalia, Clio Sport 172 and 182 , Clio RS.

Clio 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)
(Part No. 509921 / 7701051272 )
Note the oval shaped connector.

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

Start by examining the Resistor Pack. It is located under the scuttle.
Open the bonnet and it is located on the left. You need to do a little dismantling, and you will see the connector plug as shown below.

Now pull off the connector.
If your blower is totally dead: (and you have checked your fuses):
Short out from 1 to 5 in the loom connector.

If the fan now runs (flat-out) when the controls are set "on", the Resistor Pack is faulty.

If your blower only runs flat-out:
Use a meter (set to ohms) to check the Resistor Pack.
Measure from pins 1 to 5 as shown.
Testing Heater Resistor by measuring resistance
You should read (very roughly, it varies) about 2K (2,000 ohms).
If you measure a short, the Resistor Pack is faulty.

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.
