havent been here in awhile ,,im kind of new to these cars,i got a prob with 140 wiper i changed the linkage gearing ,,the $1000 part ,,my prob is when it gose to park its not going behind under the windsheild ,,,but whan its running on slow or fast it wipes like its supposed too...,,i thinks its the motor but not 100% sure???when the man dropped off to me the gears in the trans where broken the wiper were stuck in the middle the the sheild..motor was clicking ...i was told that sometimes the motor goes bad with the linkage ..go check your 140 body car to see ..on intermitt..it gose back and forth ..see if when you turn it off the wipers go behind the windsheild ,,...thanks....

 

On most cars that had a parking feature for wipers behind or better said under the top of the hood, is usually a vacuum function. But I'm not familiar with your particular setup and Mercedes does things different. I had an American car years back that had this type of parking windshield function. The motor went and I had it replaced, but it didn't park down below and behind the hood. I took it back and the mechanic forget to hook up the vacuum hose that controlled the park function. I hope this helps.

 

i think it's normal.

it doesn't really goes further down in park position.

on the glass of the windsheild, you will see a marker there for the park position. it is sometimes a dark or transparent line about 1 cm long. that is for the basic setting.

 

i found the problem, i had it out of time just a bit,,,[&o].i dont need the 500 dollar motor..hard to know where its at then its been broken...
