If the vehicles battery has been disconnected, each side door window regulator motor must be reprogrammed in order for the express-UP or express-DOWN feature to operate properly. Keep in mind, that if something is obstructing the window from opening or closing and you continue programming, the window will only express-UP or express-DOWN to the spot where the obstruction occurred. If an obstruction comes in contact with the window during the programming procedure, the procedure will have to be repeated.

The following steps explain how to program the side door window regulator motors:

  1. Press and hold the power window switch until the window is fully DOWN.
  2. Continue holding the power window switch for approximately 3 seconds.
  3. Press and hold the power window switch until the window is fully UP.
  4. Continue holding the power window switch for approximately 3 seconds.
  5. The power window regulator motor is now programmed for the express function.
  6. Repeat this process for all of the power windows.
