The reservoir is actually shared by the front, if the reservoir is below a certain level it won't squirt. So first try filling the reservoir to the top. Also inspect the rear nozzle to make sure it is not plugged up with dirt (you can try a small needle). I'm pretty sure there is a second pump for the rear, have a listen while someone operates the controls. Replacement pumps are as close as your local auto parts store.
Good luck and let us know how it works out. When I had my 99 Forester, I thought something was wrong when it stopped working.
