Hi Dell; Many thanks for your helpful reply, I am not aware if the mirror has been hit, there is no obvious damage, I only noticed it when I was washing the car and the housing moved. It shakes when the door is closed, however, no problems whe the car is driving, not even along the motorway. I think perhaps it would be best to ask a garage to have a look at it. Would you know if the weather strips are available from dealers only? I will have to make enquiries to ascertain how dificult it is change them before deciding whether to try it myself. Regards Steve
