My window wipers keep coming on and won't turn off although I can select the high speed when this is happening.this fault is only intermittent but it seems to be getting worse, I find that it seems to happen when I'm turning but I have checked the wiper stalk and wiring to the wiper motor as my strut brase was putting pressure on the wires but all look ok. I want to check the realy but don't know where it is ? Or has anyone had the same problem?
