Hello together, for 3 days my rear windscreen wiper no longer works. First I wanted to contact the fuse box. Unfortunately, the 3 box is not as described in the instruction left back in the trunk, so that this is not available??!! Just checked the cables. These are equal to the rear heating. And look, there is a break in the line. Now my question, how do I get the rear windscreen wiper released from the disk so that I can use Leitl ack a new line( the old) can brush over? I have the one screw on the right side can release only how is the connection on the right side? Thank you very much for your tips…. Greeting Bernie
