Power Window Motor: Testing and Inspection

DOOR WINDOW MOTOR INITIALIZATION

CAUTION: Make sure that no obstructions are present in the window system when carrying out this procedure.

NOTE:
- The LF window motor must be reinitialized whenever: the motor is removed from window regulator drum housing, a new motor is installed, a new window regulator is installed, a new window glass is installed, glass top run removal or installation, or when carrying out any operation in which grease or lubricants are applied to the window system. A new LF window motor will be in a proportional up/down mode until initialized.
- All LF window components (window glass, window regulator, window motor, and glass top run) must be installed and tightened to specification before carrying out this procedure.
- If this procedure is only partially completed, the LF window motor will remain un-initialized and only the proportional up/down functions will operate.
- Steps 1 through 6 must be completed within 30 seconds. The entire procedure must be completed within five minutes.
- Once the ignition key is turned to the ON position in Step 6, it must remain on until the entire procedure is completed.
- Steps 7 and 9 require that the master control switch (LF) be held in the up position until the LF window motor stalls the window glass into the upper header seal. Step 8 requires that the master control switch (LF) be momentarily actuated to the down position.

1. Start with the ignition key in the OFF position with the LF door open.
2. Turn the ignition key to the ON position.
3. Press the front window control switch (LF) to the AUTO position six times (AUTO up or AUTO down).
4. Turn the ignition key to the OFF position and make sure the LF door is open.
5. Press the front window control switch (LF) to the AUTO position six times (AUTO up or AUTO down).
6. Turn the ignition key to the ON position and close the LF door. The LF window glass will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the LF window motor has entered initialization mode.
7. Pull and hold the front window control switch (LF) to the up position until the window glass stalls into the upper header seal.
8. Momentarily press the front window control switch (LF) to the down position and release. The window will carry out a one-touch down operation until the window glass stalls at the bottom of travel stop designed into the window regulator.
9. Pull and hold the front window control switch (LF) to the up position until the window glass stalls into the upper header seal. Once this operation is complete, the LF window glass will move up-down-up-down approximately 20 mm (0.8 in) indicating that the LF window motor has been successfully initialized.
10. Verify correct operation of the LF window by carrying out a one-touch down, one-touch up, proportional down, and proportional up.
