The problem

Many Peugeot owners have experienced a problem with the heater not working properly.
Vehicles affected include the Peugeot 206 and 307.

Owners may experience an intermittent heater blower fan, on one or more of the speed settings, or the fan may not work all, or will only work on full power, or may be stuck on full power.

Two types of controls are used, depending on whether the vehicle has auto air-con or not.
Generally, it is the vehicles without auto air-con that have the most common problems with the heater and this is the vehicle we are dealing with here.

The possible causes

There are two common causes of a heater blower fan problem in the Peugeot 206 or 307 without auto aircon:
Quite frequently, both faults will be present.

A. Faulty Heater Resistor (Otherwise known as the Heater Blower Resistor, Resistor Pack, Heater Rheostat or Blower Motor Resistor, Part No. 6450JP )
Usually, it is the thermal fuse on it that fails.

B. Overheated/Burned Heater Resistor Wiring Loom Connector
The connector can become overheated and melt, causing damage to the loom.

B. Overheated/Burned Heater Resistor Loom Connector.
Replace the wiring loom connector by fitting a Repair Loom including a new connector.
(Part No: 6445KL / 6445ZL).
This 5-wire loom is suitable for repairing a burnt loom on either the Peugeot 206 or the 207.
Some of the original looms may have only 4 wires - the 5th wire is left disconnected.

C. Other Causes

There can, of course be other causes, like a faulty blower motor, or a blown fuse, but the two main causes above are far and away the most common.

Stage 1 - Investigate.

If your heater blower is totally dead, do check your fuses first.
Access to the Heater Resistor is gained from below the dash on the driver's side.

Remove the panels shown in 1 and 2 below from below the steering wheel.

7. Twist it anticlockwise, and pull the Heater Resistor back through the opening.

Disconnect the Heater Blower Resistor from the loom for inspection.
The Thermal Fuse is shown arrowed here.

Resistor pack and replacement fuse and crimps New fuse crimped in place, ready for legs to be cut off
3.Bend the legs of your new thermal fuse into a "U" shape.
4.Now crimp the new fuse onto the old legs, such that the fuse is still close to the Resistor Pack body.
Cut off the protruding legs, and the Heater Resistor is repaired and ready for re-use.

Don't forget to try and determine why the fuse failed in the first place.

Replacing the Heater Resistor Loom Connector:
To do this, you need to cut off the old connector, and connect the cables on the new loom kit to the original loom.
For safety, disconnect the battery first and make a note of the radio code.

Eliminate the possibility of making a wiring mistake by cutting and crimping only one cable at a time.

If you prefer, solder the new cables onto the old loom, using heatshrink or insulation tape to complete the installation.
