  Q: How to Initialize the Front Door Power Window Motor on Lincoln LS?

  A:

  A correct initialization of front door window motors needs an obstruction-free window system. The procedure to initialize a battery disconnect is not mandatory but repeated resilient window motion without physical blockages usually signals an uninitialized motor. Initialization of the motor becomes needed at three points: removal or installation of the motor or new component installation or application of lubrication to the window system. A correct installation and proper tightening of window glass along with Window Regulator and window motor and glass top run will enable safe system operation. The motor will operate only in proportional up/down mode when initialization fails to complete thus maintaining a non-initialized status and one-touch down functionality while disabling one-touch up. Use diagnostic equipment to initialize the system if one-touch up operations fail three times using the window control switch particularly when false bounce back occurs. Press the window control switch on its second detent at the UP position while you maintain the hold until the window reaches the glass top run before keeping it pressed for another 2 seconds. Inspection should verify proper operation of the one-touch down and one-touch up commands. disable bounce back function when operating the diagnostic tool because there must be no physical blocking objects before the tool. The testing procedure ends before starting without completing the stall measurement when a user presses a Window Switch before reaching the stall position. When using the diagnostic tool to perform the self-test the front windows will move to full open position after stalling at the header seals. Conclude testing by performing checks on the single-touch features that lower and raise the windows.

  Q: How to service the front door window regulator and power window motor on Lincoln LS?

  A:

  Service on the front door window motor and regulator starts with taking out the front door window glass. The service starts by taking out the front door inner support bracket bolt while tightening it to 12 Nm (9 lb-ft) before final installation. During installation one should tighten both front door inner support bracket securing nuts to 12 Nm (9 lb-ft). To reinstall the front door inner module assembly use a torque of 12 Nm (9 lb-ft) when securing its six bolts. Fitments that enable remote keyless entry and exterior mirrors should have their electrical connectors disconnected before the locations are released from the front door inner module assembly. Place the main wiring harness and front door inner module assembly electrical connector into a separated position before you release all locators. Remove the upper theft shield screw and tighten it to 10 Nm (89 lb-in) before reinstalling then detach the nut together with the lower theft shield. The process for the left-hand door requires disconnecting the door lock cylinder actuating rod while opening a clip to separate the exterior door handle actuator rod and disconnecting the door lock cylinder switch electrical connector when present. Separate the front door latch electrical connector while removing three screws to detach the door latch unit then place it aside before reassembly where torque should reach 13 Nm (10 lb-ft). The front door inner module requires removal before extracting the five nuts from the front door window regulator while reinstalling each nut with 5 Nm (44 lb-in) torque. Reinstall the inner door module bolts and start by tightening the two bolts situated next to the alignment dowels before seating the bolt that incorporates the alignment dowels.
