opburg89 Posted November 15, 2019 Share Posted November 15, 2019 2014 transit connect front wipers not working. Dealer replaced wiper control arm on steering column no success. Replaced both wiper motors again no success. There is 12-Volts available from the LH/RH wiper motor connector plugs but neither motor will actuate. through research it seems that there is a "wiper pulse module" located some where but have been unsuccessful in locating. Does this module exist or are the front wiper motors driven by the ECM directly? These LH/RH motors appear to be possibly individual stepper motors is this correct? I have tried to find a schematic online to help trouble shoot, but have not found any. Thanks and any help is greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Fifty150 Posted November 15, 2019 Share Posted November 15, 2019 The dealership should be able to call Ford. There's a technical support department. Quote Link to comment Share on other sites More sharing options...
G B L Posted November 16, 2019 Share Posted November 16, 2019 A high level scanner can check the wiper operation . The wiper are probably run by the body control Module Quote Link to comment Share on other sites More sharing options...
Don Ridley Posted November 16, 2019 Share Posted November 16, 2019 Wipers are controlled by the BCM and SASM (steering angle sensor module). 12v and Common are always present at the motors. A LIN signal activated the motors. I have no idea how this signal works or what the circuitry in the motor looks like. See the wiring diagram in the other wiper topic.

G B L Posted November 17, 2019 Share Posted November 17, 2019 The scan tool can cycle the wipers , if they work then the problem is not the signal. Quote Link to comment Share on other sites More sharing options...
