Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner, flashlight, trim removal tool.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect the Control Switch

Remove the sunroof control switch from the overhead console using a screwdriver.
Visually inspect for damage or corrosion.
Use a multimeter to test for continuity when the switch is pressed.

3. Check the Fuse

Locate the fuse box (typically under the dash or in the engine compartment).
Identify the fuse associated with the sunroof (refer to the owner's manual for the exact location).
Remove the fuse and check if it is blown. Replace with an identical fuse if necessary.

4. Test the Sunroof Motor

Access the sunroof motor located above the headliner (may require removing trim panels).
Disconnect the motor's electrical connector.
Use a multimeter to measure voltage when the switch is activated. If no voltage is present, the issue may be with the switch or wiring.
If voltage is present, connect a power source directly to the motor to verify it functions properly.

5. Inspect the Sunroof Mechanism

Clean the sunroof tracks with a damp cloth to remove any debris.
Check for any physical obstructions or broken components in the sunroof frame.
Ensure the glass panel is aligned correctly and can slide freely within the tracks.

6. Reassemble and Test

Reconnect any components and the sunroof control switch.
Reconnect the vehicle battery and test the sunroof operation to verify functionality.
