Yup, ProZac is right. Last month when I was reading the Owners Manual on my 2003 ES it told you how to get the windshield wipers out of the rest position by carefully pulling them up, applying about 20 foot pounds of upward pressure. I also was afraid of doing this since the force seemed excessive but I did it anyway. Sure enough the blades now were about 2" above rest position and I could change the blades because they were not blocked by the hood. On the older ES's(I think '92 to '94), you have to move the electrical contact under the hood to a different position. I never bothered to do this on my '94, but I turned off the ignition key when they were in the position I wanted so I could change the blades or wipe them off with a rag.:)
