It's a common problem with the C5.

It is the blower fan controller. This is a unit about the size of a
cigarette packet and is found in the driver's footwell on the left, fairly
high up.

Valeo part number 509355 or Citroen part number 6441L2.

Buy a new part and just plug it in, make sure the ignition is off tho ;-)

Regards

Philip

Hi I have probs on xzara piccasso citroen heater switch fan and a/c switch not working cigar lighter also not working fuzes look good


Hi Francis there is a resistor pack in the heater box that controls the speed of the fan. They eventually give up. While you are in there try powering the fan direct just to check it spinns. Regards Jim...

How do i dismantle the dashboard


Presuming your car is fitted with the automatic heating/cooling system.
There is only one fan controls the heating/cooling system the distribution from this to the various vents is controlled by a series of electronic flaps which open or close dependent on the temperature selected at the control unit.
If the motor is running and the drivers side is receiving cooling it may be a problem with the control unit or a flap has stuck open.
Replace the control unit first as the flaps are a citroen job.
Control unit is the bit with the temperature displays etc.

Picasso heater blower not working


Hi all. Yes this is a very common issue. 2 distinct issues in fact are common with the aircon.
1 you get fan on certain settings only. This is the resistor gone and johnjohn2 has identified the fix for this above. This is usually (although not always not intermittent and so you will usually lose all other settings over night and they don't come back
2 you get no fan activity at all. This starts to happen intermittently and then gets more frequent until the fans won't work at all. The fix for this is expensive through Citroen but cheap if you get the part off ebay. It is the ignition switch cable which has a fault. A very common issue. You need to remove the ignition switch and replace the cable from it. Work is not long but plugs can be tight and fiddly.
here is the link for the part

good luck

Remove heater control switch


Before removing the heater switch on this 2006 citroen hdi I would first have the blower motor checked and the most common reason for this and other blower problems would be the blower resistor.

Your blower works on and off at times, first locate the blower motor and the resistor. the blower motor is located on the heater box, look under the pass/side of the dash, you may have to remove under dash cover to see blower.
When you have located the blower now look to the side on the heater box, there you will see a connector plug, it plugs into a connection on the heater box, this will be the resistor, the resistor slides into heater box and the end of it bolts to box to hold it in place and then the connector plugs into it, if you can not locate it then follow wires that plug into blower , follow wires back they will lead you to resistor,
next time blower does not work wiggle connector to resistor and see if blower turns on, if it does then resistor is the problem. also unplug resistor plug at resistor and check for any burning of connectors at plug and inside resistor.

I would bet its a bad resistor or the plug is brunt due to high draw from bad connections, if plug has burn damage to connectors then replace the plug along with resistor.

Ac blower motor


Check fuse supplying fan is not blown,
Check blower control switch is operating OK,
Check relay controlling fan is operating OK,
Check variable speed resistor pack is not faulty (the resistor pack is usually located in the blower ducting, in the blower airflow),
Check blower motor ground connection is not missing.
