Hey guys couple questions... I really want to install my auto lambo doors and shaved door kit on my own, but don't want to screw anything up.. Any1 got a link that would help me with this.. even external sites are fine.. ive looked on youtube and havn't found much.. also went to role down my windows the other day and one got stuck and other is slow as hell.. Is the motors bad... if so how do i replace these and is it difficult.. i appreciate all your help and comments guys thanks
