Bit of a problem with the Windows on the golf they won't go up or down on either of the switches , they only way is to either lock the car and hold it to shut , or open the car and hold it to open. I thought this was a relay myself but could be wrong was also told the reverse light fuse has something to do with it

. anyone any ideas or answers even better? Also electric mirrors don't work would this be part of the same problem?
the sunroof works on the switch, when I go to open or close it will only lift one side up or down, has a cable or bar broke to cause this? I don't want to take it off because of our lovely Irish weather

If anyone could help me with this it would be much appreciated
