Skulz - First open the hood. Then have a friend spray the fluid. You should be able to hear the fluid pump with the key in acessory posistion and motor off. If you can't here it check the fuse box (inside side panel drivers side & under hood) I believe it is a 10A or 15A fuse but it is marked and identified in the book. There is also a fuse box "MAP" on the lid. If you have no luck with this (still won't spray and fuse is good) take and press the rear washer button, hold it in spray posistion and cycle key and on and off - starting engine completely. This will cycle the diognostic computer to check that circuit for an open switch or faulth to ground. If no luck with this. Take the front washer switch and press it into posistion several times (20). There is almost no chance you are clogged.
Hope this helps.
