What would cause the Servo motor to the air recirculation flap valve to emmit loud ticking every time I start my car? I have managed to prise the dash out on the near side enough for me to see the actuator arm, which seems to do its job ok, arms move, etc., but when the flap is opened to the fresh air position the motor continues to run - hence the ticking as the motor tries to drive it further. What should I check next? I don't rearly wish to take the whole dash out.

the hardest part is removing the bolts most times they are so rusted i just cut them out with a torch and replace them with the new bushings. the cost of these bushings is nominal however have you checked the struts as well? the clonking noise could be them as well. please rate this......thanks

Hi,
I think here, by your description, that there might be something that has slipped inside the vent holes from outside. you can try to blow some compressed air through the vent holes at the bottom of the windscreen.
Otherwise you can try to look under the dash, activate the switch and see if you can locate from where the noise is coming and see if you can reach the mechanism that control the vent. Normally it must be moving free. Otherwise your local mechanic should be able to fix that ufor you.
Cheers.

It sounds like you need to go to the shop. the blend doors control the air flow, heat, and distribution. There are about 6 to 7 motors in all. They most likely need to be recalibrated. There is also a possibility the Climate Control Module Software will need to be upgraded. There is a small chance that there is a bad blend door motor that is crashing the communication link between the motors and the module.

Either way it goes only the dealer, or mabey a very heavily invested independent shop.

Hope this helps.
