Well, when it works it is very slow, but more often it just doesn't move when I push the lever. Occasionally it will move about 5 inches and stop. It obviously works, so would a liberal dose of WD40 do anything or do I need to replace the motor?
In addition, when I depress the lever to get fluid onto the rear screen, the motor can be heard but nothing comes out. The fluid comes from the front washer bottle, doesn't it? Any ideas?
