Hi All I hope this is a "reasonably easy to oblige," plea for help. When I bought my "Y" reg Vectra 6 months ago I had the driver & passenger's door seals replaced as they had cracked and split! - (I have never known it on another car I've owned). Recently I have carried a passenger who told me that the door was not sealing well - I thought I had detected a slight rise in internal noise in the car, but difficult to tell from the driver's seat when in motion. Question - How do you adjust the doors properly without overdoing it? Thanks for you input and time Regards RobO
