W211 wipers stopped working

[daveW211]

today when driving, the wipers on my 2004 W211 stopped working, they were on the auto setting at the time, also noticed that when i pressed the end of the stalk they would still not wipe or wash, turn the stalk to the off position and on again and they started working.
this happened about three times this morning

One of my previous 211's used to do the same - I was told that it's probably caused by the relevant SAM having a moment. Best to get codes read if you can.

thanks i will see how it behaves next time i'm driving in the rain and if it does it again will look at getting the codes read.
