I just bought a 94 RX-7 and am trying to get it inspected. The only problem is that the wipers do not go to the 'parked' position when they are turned off, they will just stop wherever they are. I have replaced the motor with a working motor from my brothers RX-7, and it did not fix the problem. Does anyone know how to fix this? Where does the 'park' signal come from and what needs to be replaced?
