On Thursday 1st May (hottest day of the year so far), I opened the drivers side door window but found it would not close although I can hear the motor running both to open and close very briefly. Is it possible to remove the inner door panel to inspect the mechanism. With only 28,000 genuine miles on the clock from new, I can't think it is wear and tear. This is the first problem I have had in 10 years of ownership. Please advise.
