Noise in heater

Hi Bazwillrun,
Don't quote me on this but I think the heater intake and motor blower are situated in the area you describe - the cabin filter may also be located there. To me the clicking sounds like a solenoid opening and closing - this could be the one that operates the flap that controls whether air is extracted from the outside or recirculated from within the cabin. It could be a faulty solenoid or the switch that operates it - the one on the dash. I suggest you try to get access to it and check the condition of the pollen filter - if necessary remove it and see what happens. If you disconnect the electrical connection to the solenoid the flap will not operate correctly and will probably affect the performance of the air conditioning. If the solenoid is disconnected you will have to ensure the flap stays either in the open or shut position. You may be able to do this with cord or tape but it is best to keep it in the outside air position so the aircon can work efficiently and keep the cabin air fresh - otherwise you'll liable to get sleepy at the wheel. Maybe some other members can assist on this one Good luck.

have to agree, it does sound like the fresh air selector flap. Some members have reported that the flaps cause a rattle or clunk noise when the car starts or idles

I have this problem on my Renault Megane 1999 Alize. The knocking noise happens when I switch from internal to external circulation. When it happens I get about 25 loud knocks, that drives me and my family mad (suicidal they say). My car has air conditioning and an inspection of the air motor unit from under the bonnet suggests that it is difficult to fix by yourself. Not only does it have air conditioning piping emerging from the box but the box itself appears to be placed deep down behind the engine and bodywork. I'm not sure that it is possible to get to from inside the car as there appears to be metal bodywork in the way. Does anyone know whether the air conditioning unit fluid has to be drained and replaced?

Megane noisy flappy sound when ignition switched on.

When I turn on the ignition on my Megane 1.6 RXE a noisy flappy type sound happens in the front bulkhead it goes on for about 10 seconds and then everything works fine untill I start the car again. Somthing seems to be loose in the front bulhead as when you close the car door you can hear it flap could anybody point me in the right direction.
