Heater stepper motor location

Hello, I have a LHD 2005 C3. There is a clicking noise coming from the dash area. I think it is the heating stepper motor. Could anyone tell me how to access this motor please? Is it drivers side or passenger on a LHD car? Can I just disconnect it?

Hi

The motor/servo for the air recirculation is on the right hand side of the centre console as you sit in the car. On a RHD car, access is after removing the lower storage bins under the steering wheel - they just pull out.

LHD is in the same place but access will be different.






Citroen C3 Heater recirculator fault (open circuit) has some pictures too.

Thank you

There are up to 3 servos in the air distribution box. But it depends on your model.
Some have all mechanical actuation. They have cables from the controls to the levers on the box.
Some have cables to the heat and air distribution levers but have a servo at the air recirculation.
The digital climate control version has 3 servos to do all the work.
It will depend on the version you have as to which one it could be. However, as Arfur says, the usual suspect is the air re-circulation servo.
Typically one of the teeth of the gears in the gearbox of the servo gets stripped and the gears don't mesh correctly. Causing a clicking sound. Don't ask me why they break, they don't do a lot of work.
Either remove the connector from the servo (to stop it clicking) or replace the servo. Note the numbers on it and do an Ebay search.
For a left hand drive car you should be able to gain access by removing the cover under the glovebox.
