I have a 19 plate E pace and for some reason the front wipers have stopped working on the rain sensor. They work when you pull the stalk forward to wash the windows but when turned on in normally and it’s raining nothing happening.
The rear wiper is working normally on the stalk.
Was thinking about disconnecting the battery to see if everything resets but sure if that’s a good idea or not?

Thanks

 

Welcome to the forums.

first go to the new members area, and introduce yer self.

Then try to clean the windshield focusing on the areas in front of the rear view mirror. I don’t have a schematic for your car, but there might be a dedicated fuse.
