So I ask many questions on here because I have bright ideas which I think on yeah I can do that , well I cant ! Wanted to change blind on my fiat 500 so I took it out , gave up changing it and put it back in which is a pain in a** . Anyway it's in but now it wont roll back unless I manually feed it though. Is there supposed to be some tension in the twisty things at the end or what have I done wrong ??
