my 2001 clk 430 left turn signal stays on. Even when I remove the keys! I think it's my combo switch, because I'm also having issues with my washing fluid. it keeps spraying no matter what! the only way to stop it is to remove the fuse. the wiper arm works just fine, but the sprayer motor will just keep spraying unless I take the fuse out! Now the same is true for my left turn signal! I hope somone helps me soon! :crybaby2:
