I followed a very old thread, and youtube videos for installing new cables and locking mechanism on the sunroof portion of the top. Everything seemed easy enough to follow however the slide isn't sliding as it should.... it is extremely hard to move on the rails and when reconnecting it to the motor it slips due to the resistance. I do not want to damage the motor so I stopped trying. It can be manually cranked, with a lot of force though. We removed the cables, cleaned the tracks, put a bit of white lithium grease in the track and its still the exact same. What are we doing wrong??? Now my local garage wont work on it because we bought the parts ourselves and it seems like no one is active anymore who can help..... I guess i just want to know if the resistance on the track is normal and maybe there is more wrong elsewhere, or if its something with how the mechanism is lined up possibly? Just desperate for new ideas
