Be aware that the 2 & 3-speed wiper motors use different link rods and various other parts.
You can't replace a 2-speed with a 3-speed without the wiper specific hardware.



How do i know which harware I have? My car had a 2 speed switch in it with a 3 speed wiper when i bought it. It worked 'okay' then but seems I do remember the link rods slightly hitting somewhere. I tried a 2 speed wiper at one time and I believe it worked fine. So im guessing I need the 2 speed unit but how do I know for sure what hardware I have?
