My 2002 MC has one windshield spray coming out on the passenger side, but no spray coming out of the driver side. I can hear the motor is working. What could be the issue? I have already try putting a pin in the hole spray and nothing happens.

I cannot find a diagram of the wiper from the manual book how the hoses are connected.

I think I may have a leak, but I don't see any leak anywhere.

Any advice?

Thanks.

 

It's prob clogged. Disconnect the line from the back of it and then press the button to see if it comes out there. Then you will know if it's in the nozzle or in the line back to where it Ts off the other side.
