ok ,i checked the FAQs and there was some info but i gotta know. has anyone ever tried to put a NEW cable in their window lifter? i have the newer style but the yahoo who had the car before me put some funky amp-thingy in the door with the new speakers. in doing so he(or she!) ran long screws to hold it in. one of them was rubbing on the cable. now it's really frayed,won't go up or down and is holding by ONE strand. i've got plenty of mechanical know how i just wonder if someone tried this and any quick tips...thanks
