2001 Pontiac Montana van, the rear window washer does not put out the cleaning fluid?

Have someone push the washer button while someone else goes back to the rear and listens for a humming noise. if there is no noise then the little pump that shoots the fluid out is not working.
If there is a humming noise then the line is clogged.
hope this helps

Our 2000 Montana had the same problem. Check the line coming off the fluild tank under the hood. One line goes to the windshield, the other goes to the back window. Have someone push washer button as you look at the line to see if it leaks. If so secure with small hose clamp.
