Hi Anybody know how to get inside the Cab windscreen surround as I have an awful rattle coming from a loose screw or something in there? Below 40mp0h its like a Western Union telegraph operator doing his thing and is really getting on my nerves. I had a new windscreen fitted about 6-8months ago and gained a 'buzz' under hard acceleration just after that. Now its become a rattle as the thing causing the buzz seems to have come loose completely. Its deffo from the upper surround and not from the dash binnacle. I need to take the outside cowl off just where the drivers side roof attachment hook goes into it's 'slot'. Possibly I need to call Autoglass out again as they fitted the screen in the first place but its been so long since they did it not sure if they would. Any ideas would be appreciated.
