2004 Peugeot 206 resistor

Is it the radiator fan or the heater fan?

If it's the heater fan .

Go to peugeot give them your car reg and get a replacement rheostat or control resistor as they are sometimes known for the heater.

Then go home!

Make a nice cup of tea as you will be going a while!

Then get hold of a Torx 20 Screwdriver and a torch.

You will need to take out the Glovebox so you may as well empty it first.

You need to take the cover off the Glovebox open it but don't let it all way down just pull it out while it's still vertical otherwise it doesn't come out.

Then you need to take out the screws behind the Glovebox cover with the T20 screwdriver and also if you look closely there is another screw inside the Glovebox facing upwards, ( I missed that for a while! )

OK once you have taken all of those out you should be able to push the Glovebox down and out there will be some wires attached to the left hand side, detach them taking note of how they go in.

Right Glovebox out!

Now you need to take out the fan blower.

SO what you need to do is stick your torch and head in behind the Glovebox and if you look as if towards the central console but from behind you will see a round looking object with one screw in.

You need to take that screw out and then turn the thing clockwise. ( This will be really really tight so you need to twist hard, it took me a good few attempts )

Once you have dislodged it there is a clip that goes into the top of the fan for the power, you must take that out and then pull the blower out.

Once you have done this you can reach inside the air duct and you will feel the rheostat. Grab hold of it, twist it to unlock it from its place and pull it towards you.

Once you have done that, then just unplug it out of the socket and then plug the new one in, then push it back to where it was and twist it back to lock it into place.

Put the fan back in and plug the wire in making sure you don't get the wire caught in the air duct.

Screw fan screw back in.

Replace Glovebox!

your done!

Radiator fan.Never done one , but this might help you .

Peugeot 206 engine cooling fan wiring and relays.





Faults we have had.

Cooling fan not working and car boiling over due to very badly corroded wires at relays and wires broken off.

Low speed cooling fan not working and water temp getting too hot and temp gauge reading about 90 degrees and then going rapidly in red / hot area and dash flashing “STOP”. Cooling fan then cuts in at fast speed. Fault was corroded connector at low speed fan resistor.



Parts of system and prices approx may 2008

Cooling fan

Low speed relay x £4.00

Fast speed relay x £4.00

Low speed fan resistor £5.00

Coolant temp sensor (green colour) £18.00

Cylinder head temp sensor (blue colour) £8.00

Fan wiring harness assembly repair. £40.00



Main fan controller Possibly called Bitron fitted near left hand bulk head unit or later cars BCI unit



The cooling fan can be operated using the Bosch KTS or other diagnostic/ scan tools machines in the functions testing area.



The operation of the coolant temp sensors and the fan relays can be checked using the Bosch KTS in the live data area.

3 areas too look at.

Select coolant temp sensor.

Fan relay operation on or off.

Fan relay %



I believe the system works something like this.

With the engine cold the cooling fan is off.

When the engine is running the water temperature slowly increases and the green temperature transmitter varies its resistance and at about 96 97 98 degrees C the low speed fan should come on cool the engine and then switch off again and continue cycling like this.



If it’s a very hot day and the water temp gets a little hotter the relays then bypass the resistor and the fan then works at full speed.

This also happens if the car has got air con and is turned on.



If the coolant temp sensor should be faulty and go open circuit or if you unplug it a fault code will be logged and then operate the cooling fan very briefly ½ a second or so at low speed and then go to full speed. ONLY WTH THE ENGINE RUNNING.



If the slow speed fan should not work for any reason the water temp will increase slowly to about 96 97 98 98 degrees and then the temp gauge will move very rapidly from the normal area to the red/high temp area. The dash display will then flash stop.

Cooling fan then cuts in at fast speed.


The 2 radiator fan relays are situated behind the front grille. When standing in front of the car they are to the left of the radiator behind a plastic cover held on by three plastic scrivets/poppers.



To remove them remove the screws securing the black plastic trim around the bonnet catch.

Then remove the painted trim that goes across the car and under both headlamps 3or 4 screws and then two trim clips at the very end on either end. The clips on the end can be removed by putting a trim removing tool behind the trim on the very end and levering the trim forwards away from the car. They are quite tight don’t scratch the paint.

You can then reach in and using a trim tool pull the heads out of the 3 scrivets / poppers. Remove the plastic cover and you will see the 2 fan relays. The original Peugeot ones are green colour.



The low speed fan resistor is fitted near the fan relays but lower down and inside the cowling of the radiator fan. It is held on by one 10mm headed bolt. Access to this is a bit tight and can be accessed from under the car by undoing the two 10mm bolts holding the lower side of the bumper. The Bosch type electrical plug is tricky to get off due to lack of space to press in the metal locking clip. I did this using an old screwdriver with the blade sawn off and a V shaped groove cut in. The clip holding the wiring loom to the radiator cowling can be eased out by using a long screw driver and the wiring can be pulled out below the car just enough to clean the plug connections of the resistor plug.

check engine cooling fan fuses in underbonnet fuse box check relay connections for corrosion check fan motor is working using direct feed or power probe you may need the services of an auto electrician

it the fan
on the readetor

the resistor is in the fan cowling and can be seen through the radiator grill in the front bumper.itis to the left and is held in place by a torx 30 screw
