2009 670 windshield washer

Behind the batteries on the left side when you're looking straight at the batteries put you're head back there and see

 

Behind the first battery is where the tank starts its small nothing big follow the electrical wires you should have one harness going down with two connections one for level sensor and one for pump just follow the electrical wires you can also follow the filler neck to find the tank.

 

How do you know it's a motor?

 

Mine would work after I flip it couple times. Turned out it was cracked filter. There is a check valve there too, and if it was bad it would work after you try couple of times. I suppose that if you had a big leak somewhere you would see it. Good luck
