I am getting fluid to the spray nozzles - it gushes out when I disconnect the hoses from the nozzles and turn the pump on. Does anybody know what the purpose of the wires that go to each spray nozzle? Is there some electronic control for each nozzle?

They are heated so they don't freeze in the winter.

It sound like yours are clogged. Time to clean them out or buy some new ones?

Hello..... it seems there are two pumps on my ML320 washer fluid reservoir. Any reason? Is one for the rear ? They look the same. The connector on the one that leads to the windshield is getting power, so the pump is bad. Thanks.
