I removed the top air vent from my dash as you showed on your how to guide to fitting the bluetooth handsfree kit because it was vibrating and buzzing at over 90mph on the motorways. So i took it apart and put a little grease around it and sure enough it stopped the buzzing. The problem is the small panel that fits around the wheel that contols the airflow doesn't seem to have gone back properly. The right hand side won't click down firmly no matter how much pressure i put on it so i can lift it out easily if i put a finger nail under it. I can't remember if it was like this before i took it out or not. I've checked that none of the plastic clips have snapped that hold everything in place but for some reason it doesn't seem right. Can you help?
