Before I bought my car I noticed a knocking/clicking noise when the mirrors went in auto. The sales guy said it would be sorted by pickup 2 weeks after, anyhows I got a lift to the dealer around 4.30pm and got ready to take my car home, only to find the noise is still there. The Windows click when going in and there's no smooth action. To save travelling 2 hours back, can I sort this myself with some oil? If so how? Thanks.. Oh and also the fog light was smashed and only just realised GREAT
