Ds4 Heating Fan Not Working

[forestpct]

The heating fan on my 61 plate DS4 1.6 HDi 110 has stopped working. Citroen dealer says it's a £600 job to fix ("new motor and control unit")!!  Before I spend this sort of money have Googled problem and there are some suggestions to try replacing the blower fan resistor.  Have tracked one down on EBay but can anyone offer advice on how to access the part and replace it?  Image of the part is attached if that helps.

 

Many thanks

Welcome to the forum.

 

The speed controller may be Citroen part 6441AA but this should be checked using your VIN. To replace it is just under half an hour, similar if the blower needed replacing so they are not big jobs.

 

This is from the Citroen service box workshop procedure but before starting I would have a look at the heater unit from the left footwell to see if you can see the blower and its controller: To replace the controller first you should disconnect the battery but this may not be necessary since most procedures say this. Then remove the square cowl under the steering column - this might only be for left hand drive cars. Then unclip and move to one side the tyre pressure monitoring ecu. Remove 2 bolts and a bracket - not sure what this is but needs removing to get to the blower left hand side where the controller is fastened. Disconnect the controller connector, unlock it, slide it up and back and then pivot it to towards the centre of the car to remove it.

 

To remove the blower also needs an air duct removing, a flap motor and then the blower can be twisted and removed. The procedures say to remove the accelerator pedal as well but this must be for left hand drive cars.
