I am sure this topic has been done to death and have searched for answers

I have a few issues going on with my windows so I hope you can help me,
1) Drivers door motor runs freely up and down when not mounted to the regulator, when mounted it will only wind windows down but when you try to wind up it does series of about 5 clicks and stops. New regulator installed last night so Suspecting it is motor/bushes

2) Passenger front goes down but to get back up you have to find right spot in switch and only by using the door switch to go back up and it does so slowly

3) RHS rear regulator drive gear is at fault, did read on one post where someone has has drilled hile onto drive gear and hammered nail into hole but for the life of me cannot find thread again.

any help on the above would be gratefully appreciated
