The problem is the linkage to the wiper motor can be placed anywhere in 360 degree from the next linkage. The wiper motor only spins in one continuous circle. So where you mount that linkage to the wiper motor must be optimized to stop the wiper in the proper position. It is a pain in the <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> to keep mounting an unmounting the plate that holds the wiper motor and removing the linkage to the motor. You can also place the linkage in a position that jams the linkage that will destroy the motor. I have not done that yet, but it is possible. Any got a picture of the correct position? <img src="/forums/images/graemlins/confused.gif" alt="" />
