Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and a trim removal tool.
Disconnect the vehicle’s battery to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate Fuse Box: Refer to the owner's manual to find the fuse box location.
Remove the Cover: Use your hands or a flathead screwdriver to pry off the cover gently.
Check Fuses: Identify the power window fuse and inspect it. If blown, replace it with a fuse of the same amperage (usually 20A).
Reassemble: Replace the fuse box cover securely.

3. Test and Replace Window Switches

Remove Door Panel: Use a trim removal tool to carefully detach the door panel clips and screws. Lift the panel upwards and disconnect any electrical connectors.
Test Switches: Using a multimeter, check for continuity across the power window switch terminals. If no continuity is detected, the switch needs to be replaced.
Replace Switch: Remove the faulty switch from the panel and install the new switch. Reconnect the electrical connectors and reposition the door panel.

4. Inspect Wiring and Connectors

Visual Inspection: Check the wiring harness for signs of wear, fraying, or disconnection.
Repair/Replace Wires: If any damage is found, repair the wires using solder and heat shrink tubing, or replace the wiring harness if necessary.

5. Inspect and Replace Window Regulators

Check Regulator Function: Manually operate the window to determine if the regulator is stuck.
Remove Regulator: If necessary, remove the window regulator by detaching it from the door frame and disconnecting the motor.
Replace Regulator: Install the new regulator by reversing the removal process, ensuring all screws and bolts are tightened to manufacturer's specifications.
