Ive had my 01 c320 for a while now, but recently it has started to make a wierd clicking noise when i start the car up. The noise seems to originate from the vents somewhere. It clicks about 5-7 before the clicking goes away. Each click is about 5 or 6 seconds apart. The clicking only occurs when I first start up the car.
Anyone know what might be going on? Or how i can fix this? I have made some attempts to find where the sounds are coming from, but its very difficulty to pin point.
