Problems with central aerators result megane

Hello I have a problem with a Renault Megane 1.9 130 hp of 2007.
When I put the heating it makes me a noise inside the central aerators, I do not know what is due and I would like opinions about it and how I can repair it thanks

Hello, try by disarming the forzator and lubricating the insurance bushings is full of dirt and draws the antipolen and changing it or insurance torch will be solved

Hello partner and thanks. Do I have a small problem the forzator to refer to the aerator disassembled? And antipolen filter where it is. Thank you very much again

Calmate, first of all your car has an electronic air conditioner or has normal air conditioning, because then it is also the step by step that moves the air distribution cover, which is blocked and if so there is little to do after what type of noise makes you, explain a little and then we will see what it can possibly be.-
