Rear Window Washer not working
 

Hi folks, when I press the button for the rear window washer, no liquid comes out the back - but a little squirts out on the front windshield from both ports. Any ideas what up or where to begin troubleshooting?
Thanks

First, the obvious question: Got fluid?

Next I would trace the system from the reservoir to the nozzle and make sure there are no leaks. Lastly I would try to determine if the pump works.
