I have a 2001 my CLK 230. Last weekend on the drive back from Caister the wipers and indicators stopped working. Not very good with electrics so I thought I might enlist the help of other more knowledgeable on here. I have checked all fuses/connections but all ok. However when removing and wiggling the turquoise plug from the wipers they began to work sporadically. I then began to believe that there may be a problem with sam unit which sits underneath. This has now been replaced but the problem still exists. Has anybody else encountered something similar?
