1995 Polo 1.0L Fuse Board Problem

Hi all

I have a 1995 Polo and it has a fuse board problem,now and again it cuts all power to the car,i have checked all connections on

the back and they are all ok,i have to leave the board hanging in the foot well because sometimes if you lift it up it cuts all power

but on other times you can move it about all you like and it does nothing all is fine,so i am left wondering what it could be,has anybody

had the same problem or know what it may be ?.

I have tried moving the fuse board down and out so i can see the back of it better but it just does not want to move a great deal once

it is un clipped from the cradle,and also the rear wiped does not work since this problem but the washer does.
