1996 Plymouth Voyager wiper motor arm assembly

I do not follow what you mean there is no reset button for the wipers. If you replaced the wiper motor and it will not park the wipers in the right spot then you hooked it up in the wrong possition at the motor. So what you need to do it unhook the wipers from the motor and turn the motor on and off again this will park the wiper motor. Then put the wipers in the right possition on the window and then hook it up at the motor and that should put it where it belongs.
