⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the vehicle's 12V battery before working on electrical components to prevent shock or short circuits.

Symptoms

•Power window switches do not respond when pressed
•Windows remain fully closed or fully open without movement
•No sound from window motors when attempting to operate
•Check for any warning messages on the vehicle's touchscreen
•Other electrical features (e.g., door locks, interior lights) functioning normally
•Possible intermittent window operation before complete failure

Diagnostic Steps

1
Verify that the vehicle is in 'Park' mode, as power windows may not operate in other modes.
2
Check for any blown fuses related to the power window system using the vehicle's fuse panel.
3
Use the touchscreen to check for any software updates or error messages related to the windows.
4
Inspect the power window switches for physical damage or debris that may obstruct operation.
5
Conduct a reset of the vehicle’s electronics by performing a soft reset of the touchscreen.
6
Test each window’s motor directly by accessing the motor wiring harness and applying power to see if the motor operates.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Screwdriver set
•Multimeter
•Trim removal tool
•Pliers

Parts Required

•Replacement fuses (as needed)
•New window switch (if faulty)

Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.
Tools Required:
- Screwdriver set
- Multimeter
- Trim removal tool

2. Inspect and Replace Fuses

Locate the fuse panel, typically found under the dashboard or in the frunk.
Identify the fuse for the power windows using the diagram on the fuse panel cover.
Remove the fuse using pliers and check for continuity with a multimeter.
- If the fuse is blown, replace it with a new fuse of the same amperage.
- Reconnect the battery and test window operation.

3. Access and Inspect Window Switches

Remove the door panel using a trim removal tool to expose the window switch assembly.
Disconnect the window switch connector and inspect for corrosion or damage.
If necessary, replace the window switch with a new component.
- Reassemble the door panel and reconnect the battery before testing.

4. Inspect Power Window Motors

If the switches are functional, access the window motor by removing the door panel.
Disconnect the motor's electrical connector and test for voltage using a multimeter while operating the switch.
If there is voltage present but the motor does not operate, replace the window motor.
- Reinstall the door panel and reconnect the battery, then test the window operation.

5. Reset Window Calibration

Reconnect the vehicle’s battery.
Perform a window reset by holding the window switch in the up position until the window reaches the closed position, and continue holding for an additional 5 seconds.
Repeat for each window to recalibrate.
