I have an intermitent problem with my 1995 W202. The wiper would swipe once or twice in a row by itself and then stop. This happened in 4 different occassions. Apart from this, the wiper works fine in all three mode. Can someone point me towards the right direction in resolving this issue ? Thanks in advance.

Anyone ? Any information is appreciated. Could it be the wiper relay ? Thanks !

Your wiper arm is in need lubrication. My 97 C230 was doing the exact same thing. The cover will need to be removed on the wiper arm and then just spray on some white lithium grease. I did it once 18 months ago and it's worked perfectly ever since. The problem was in the cold months (below 32 degrees f).

Make sure you have the wiper in the middle of the windscreen when you do it. The piston rod arm will be extended.
