I have a SJ Nissan almera, the problem is that the front wipers go on full no matter what position the switch is set to, and the only way to stop it is to actually stop the car then switch of the engine! I have had a mechanic look at it before and he changed the wiper motor, this has worked for a little while but has now gone back to the same problem. Can anyone please help??
