Fairly new member here, although I have lurked for years... Could anyone help me trouble shoot a problem with my 1994 E420 windshield washer? The fluid will not squirt out of the windshield jets. I have replaced the washer pump and checked all the hoses and fuses - all appear ok. The jets themseves are not clogged. The turn signals and the wiper itself is working, so the steering wheel wiper control stalk is probably ok, but I suspect that voltage is not getting to the pump. Is there a relay that could be the culprit? Any advice would be much appreciated. Thank you.
