Solution

1. Preparation

Gather tools: socket set, flathead screwdriver, multimeter, lubricant (silicone spray), and a clean cloth.
Disconnect the vehicle battery to prevent any electrical shorts.

2. Inspect and Clear Obstructions

Remove any debris:
- Use a flathead screwdriver to carefully pry off the sunroof trim if necessary.
- Clean the sunroof track with a cloth and ensure no foreign objects are present.
Apply a lubricant to the sunroof track to facilitate smooth movement.

3. Check Electrical Components

Test the sunroof fuse:
- Locate the fuse box and find the sunroof fuse.
- Remove the fuse and check for continuity using a multimeter. Replace if faulty.
Test the sunroof motor:
- Disconnect the motor's electrical connector.
- Use the multimeter to test for voltage at the connector while operating the switch. If voltage is present and the motor does not operate, the motor is likely faulty.

4. Motor Replacement (if necessary)

Remove the sunroof motor:
- Access the motor by removing the headliner if required.
- Unscrew the motor from its mounting using the socket set.
- Disconnect the wiring harness from the motor.
Install the new motor:
- Connect the wiring harness to the new motor.
- Secure the motor in place with screws and reattach the headliner if it was removed.

5. Test Operation

Reconnect the vehicle battery.
Operate the sunroof switch to check for proper function.
Observe the sunroof movement for any unusual sounds or hesitations.
