W211 windscreen washer fault

Hi everyone, I am new to this group and would appreciate some help.
I have a 2004 W211 and the windscreen washers won't work. I have replaced the pump but they still do not work. Am I right in thinking that if the SAM unit was faulty the headlamp washers would not work either and it is more likely to be the indicator stalk that is faulty.


Regards.

Thanks for your reply. This morning the washers started working again but not as powerful as before. Maybe the new pump I put on is not as powerful but I have now got to wait to see if they pack up again.

Also make sure all of the fluid lines are connected, that is an issue on these cars
