Hi, I have an E220CDi '06. Recently after a very cold spell I noticed windscreen washer fluid was going "missing". I also found that the drivers side headlight washer was just pouring out fluid when the button is pressed. I reckon the nozzle needs replacement. Is it OK just to prize the cover open to access the nozzle, or do I have to approach it from behind? Also if I press the button and immediately pull the fuse, will it stay out then?
Hope someone can help,
Thanks!

 

On my E500, I found that the covers are hinged, but you can't replace the nozzles from the front. Actually, the entire bumper cover has to be removed, and the nozzle is held in place by one bolt. That bolt is close to the inboard lower side of the headlamp.
