Rear window washer sprayer didn't work. I checked under the hood located a hose that came disconnected. attached it and it worked for a while. Then all of a sudden no fluid coming out of sprayer again. Checked under the hood again everything was connected. Some where towards the back is where I suspect a hose has been disconnected. I just haven't had the patience to try to locate it. So I do with out a washer fluid sprayer for the rear window. So many problems with this generation explorer.
