How to Replace the Radiator Fan Resistor on a Peugeot 206

This guide explains how to replace the radiator resistor on a Peugeot 206. The vehicle indicates a problem, alerting us with a solid yellow light with a triangle, which means engine control system anomaly. Connect your Multiscanner to the OBD port, which in the Peugeot 206 is located in a compartment between the steering wheel and the driver's door, and check what the issue is. The scanner does not detect any engine errors, indicating a resistor problem; indeed, the temperature is at 90°C and the fans do not start.

Open the bonnet: the resistor is hidden under the intake duct, which can be removed easily. Remove the resistor, which is secured by a single bolt.

You can find the replacement for about £13 from a parts supplier or on major e-commerce platforms. Reconnect it and screw back the bolt you previously removed.

Refit the intake duct that you took off to carry out the work. To reset the light, follow this unusual procedure: close all doors, remove the ignition key, and wait for 3 minutes.

Disconnect the vehicle's battery and wait for 15 seconds. Reconnect the vehicle's battery and wait for 10 seconds (without opening the doors).

Turn on the side lights through the driver's window. Turn the ignition on and check the system's functionality.

Press the lock button on the key for 10 seconds. Remove the key, open and close the doors, start the engine, and complete the system check.

It seems that this entire procedure is essential.
