my front window whiper (if thats how you spell it) stops working every now and then.... it's just like it need some help to get started, then it can work for a couple of weeks before it's stops again and need some help to start... and it starts of slow and it's just like it needs to run the panorama a couple of times before it realy kicks in...

any idea what this could be ??? do i need to have some grease or something on it ???

Possibly it needs the drive head lubricating, if you keep using it like this you will damage the drive gears and a new drivehead is very expensive.
For instructions on lubricating, see here ; http://202tech.mkosonen.com/howto/wiper.html .

And it's "wiper".

no H in wiper

thnks for the link, that sure did the job. It was a bit different from the picture but worked perfect. I also went in to a MB dealer and asked and got a tip about cleaning it up first using some CRC 5-56 before adding white lithium grease...

Now it runs perfect...
