Hi.My rear wiper motor started leaking washer fluid into the boot so i replaced the wiper motor with one from a MK 4 Golf.Fitted perfectly on to the 3 fitting bolts and the wiring plug connected up perfectly.The problem is that the wiper now comes on and wipes the back window about 6 times every time you turn on the ignition regardless of the position of the switch.It seems to have a mind of it's own.
