So I don't know what's going on with my windshield wipers!! On setting one it goes for a while then will randomly shut off sometimes it will come back on several minutes later like 15 minutes later lol and other times it won't come back on at all. And for setting two and three it squirts out windshield wiper fluid! WHAT GIVES?! It's a 2004 c230 with rain sensing wipers if that helps any!

 

Test your comb switch, front wiper relays and or SAM----If you don't know where they are do a google search and or youtube vid--there are 1000's out there!!

 

how could i tell if the relay is bad? took it out n well can't see in it like typical fuses to see if it is blown. Was thinking of swapping it with a different relay but didn't know which one i should switch it with without causing more problems!

 

This is HS electrical stuff chum---very simple follow the schematic printed on the relay---apply 12V---do you hear a click= OK--no click=no goodie!
