my Genesis G70 electric windows won't work, what should I check

Solution

1. Preparation

• Gather required tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

• Locate the fuse box according to the owner’s manual.
• Remove the power window fuse using a fuse puller.
• Inspect the fuse; if blown, replace it with a fuse of the same amperage (typically 30A).
• Reinstall the fuse and reconnect the battery.

3. Inspect and Replace Window Switch

• Remove the door panel using a trim removal tool.
• Disconnect the window switch connector.
• Test the switch with a multimeter for continuity.
• If faulty, replace with a new switch and reconnect.

4. Test and Replace Window Motor

• If the switch is working, remove the motor from the door panel.
• Apply direct battery power to the motor terminals to check functionality.
• If the motor does not operate, replace it with a new window motor.
• Reinstall the motor and reconnect the harness.

5. Check Wiring Harness

• Inspect the wiring harness connected to the window switch and motor.
• Look for signs of fraying, corrosion, or disconnections.
• Repair or replace damaged sections as necessary.
