Rear window washer does not work what should you check first clogged line motor where is it located in the headliner?

I would first check the nozzel, it might be clogged. Check and listen if the pump is working. You should be able to hear it pumping. Check the lines from the resivor in the engine compartment back as far as you can. If pump is not working it might be a fuse. Hope this helps!
