how to clean clogged windshield washer nozzels??

My 2001 S430 has two completely clogged windshield washer nozzels. Only the passenger side works. King of a driving hazzrd. I tried to find past threads on it, but couldn't found any. Can someone advice, how to clean these clogged nozzels? Thanks in advance.

Any idea what might have done it?


I'm guessing you've tried Windex, Targone, uhh eating the tacos on top of your spray nozzles. If not, try those first.

If those don't work, remove the hood liner to see if the lines are actually connected. They might have popped off and are now spraying the inside of your hood.

If they're connected, follow the lines and see where they might be broken. Poke them too, see if liquid is inside them. If not, blockage might be all the way through the reservoir.

Just start at the nozzles and follow the yellow brick road, it can only be a blockage, a loose line, or a broken line. Not complicated, just annoying.

The local MB Tech used a sewing needle according to the size of the nozzle to clean it. Be carefull when inserting it not to make a hole inside the nozzle. These can get clogged from dirt - wax - polish. When wash an wax always check it after drying or finishing detailing.

Good luck.
