How To Reset Power Window Motor (Reset Switch And Pulse Switch)

WARNING: This page is about a different car, the 2002 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

It is necessary to reset the power window motor (in initial position for the limit switch) when separating the window regulator from the power window motor or operating the window regulator with the door glass not installed.

If the jam protection is not functioning properly, perform the following procedure:

    NOTE: Place the matchmarks on the power window motor and window regulator gear.
  1. Remove the power window motor.
  2. Connect the power window motor and power window switch to wire harness of the vehicle.
  3. Turn the ignition switch ON and operate the power window switch to idle the power window motor in UP side direction for more than 6 or less than 10 rotations (4 seconds or more).
  4. NOTE:
    • Install the motor when the regulator arm is below the middle point.
    • Align the matchmarks on the power window motor and window regulator gear when installing the power window motor.
  5. Assemble the power window motor and regulator.
  6. CAUTION: Never rotate the motor to the down direction until the completion of the window glass installation.
  7. Assemble the power window regulator and door glass.
  8. Connect power window switch to wire harness and turn the ignition switch ON.
  9. Repeat UP and DOWN operation several times manually.
  10. NOTE:
    • Take care that the jam protection function does not operate just after resetting.
    • Reset the regulator again when performing the reverse operating after closing the window fully by AUTO UP operation.
  11. Check if AUTO UP and AUTO DOWN operates in automatic operation.
  12. Check the power window function.
