How do I repair my rear washer?

Dear Candace-  It sounds like the tubing for the rear windshield washer has become disconnected on your 1995 Chevrolet Blazer.   By going to the following site, meant to describe how to access the rear wiper motor, you will learn how to expose the inner working under that rear door and you will see your problem clearly--  http://autozone.com/servlet/UiBroker?ForwardPage=/az/cds/en_us/0900823d/80/18/bf/20/0900823d8018bf20.jsp.  Either repair the tubing or replace it.   Good luck from Bovan.

Dear Bovan,
Thank you so much. I took it apart once but really had no idea what I was doing. I find it much easier to work with the illustrations from this site as well as the instructions. Thank you so much. Candace
