The windshield washer on my 2006 E320CDI is not working: I push and hold the button and get only one complete sweep of the wiper - no pump sound, no squirting, only one sweep of the wiper no matter how long I hold the button.

The problem originally showed up with a "washer fluid low" light on the dash, so I figured I was just out of fluid, but refilling the fluid hasn't helped. I've looked for a fuse that might be the culprit, but none of them are labeled for the washer pump.

Any advice is greatly appreciated.

Best Regards,
Rob
