1. Check the fuse. The first thing to check is the fuse for the power window. The fuse box is located under the dashboard, on the driver's side. The fuse for the power window is usually labeled "PWR WDO." If the fuse is blown, replace it with a new fuse of the same amperage.
2. Check the power window switch. If the fuse is not blown, the next step is to check the power window switch. The switch is located on the driver's door, next to the armrest. To test the switch, turn on the ignition and press the power window switch up and down. If the window does not move, the switch may be faulty and will need to be replaced.
3. Check the window regulator. If the switch is working properly, the next step is to check the window regulator. The regulator is located inside the door, and it is responsible for raising and lowering the window. To test the regulator, remove the door panel and look for any damage to the regulator. If the regulator is damaged, it will need to be replaced.
4. Check the window motor. If the regulator is not damaged, the next step is to check the window motor. The motor is located at the bottom of the door, and it is responsible for driving the regulator. To test the motor, apply 12 volts of power directly to the motor. If the motor does not run, it will need to be replaced.
5. Check the wiring. If the motor is working properly, the next step is to check the wiring. Look for any damaged or loose wires. If you find any damaged wires, repair them and then test the window again.
6. Reset the Power Steering. If the front passenger window still doesn't work, you could try resetting the power steering by turning the ignition key to the "On" position and holding the power steering button up for at least 1 minute. Hold down the button until you hear a click and the window resets itself.
If you are still experiencing problems with the front passenger power window, you may need to take your car to a qualified mechanic for further diagnosis and repair.
