You guys seem to really know about the different wiper motor assemblies. I have a 2 speed motor and now know the switch is a variable speed switch. The wipers have never parked correctly or worked well in any way. Is the 2 speed motor supposed to be with a variable speed switch? What motor is supposed to be with a variable speed switch. I would like to keep the 2 speed motor in the car so I guess I need to find a 2 speed switch. Are they still available in the parts stores or do I need to find one in a salvage yard? Also, I saw the post about the cam being on the arm assembly. Do you guys have a pic references so I can compare to what I currently have?
