Front passenger window not working properly

Welcome to 2CarPros.

It sounds like the window regulator has failed. On this vehicle, the regulator contains a cable and I suspect it has broken or something has come disconnected.

What you need to do is remove the door panel and inspect the regulator to make sure nothing has become disconnected.

Here are the directions for replacing the regulator. The attached pics correlate with the directions.

5. Install the glass and regulator in the reverse order of removal, and note these items:
-Roll the glass up and down to see if it moves freely without binding.
- Make sure that there is no clearance between the glass and glass run channel when the glass is closed.
- Adjust the position of the glass as necessary.
- Check for water leaks.
- For '03-04 models: Reset the power window control unit.
- Test-drive and check for wind noise and rattles.
- When reinstalling the door panel, make sure the plastic cover is installed properly and sealed around its perimeter.

Since you hear the motor running but the window isn't moving, this is my first suspect. Let me know if this helps or if you have other questions.

Take care,
