Solution

1. Preparation

Gather tools: flathead screwdriver, Phillips screwdriver, socket set, multimeter, lubricant, and a clean cloth.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clear Tracks

Open the sunroof fully (if possible) to access the tracks.
Use a clean cloth to wipe down the tracks and remove any debris or dirt.
Apply a silicone-based lubricant to the sunroof tracks to ensure smooth operation.

3. Assess and Fix Alignment

Check the alignment of the sunroof by observing its fit within the roof opening.
If misaligned, loosen the mounting screws on the sunroof assembly using the socket set.
Adjust the sunroof to align properly and retighten the screws to the manufacturer’s specified torque value (typically around 10-15 Nm).

4. Test the Motor and Wiring

Reconnect the battery.
Use a multimeter to check for voltage at the sunroof motor when the switch is pressed.
If no voltage is detected, trace wiring back to the switch for any breaks or shorts. Repair or replace as necessary.

5. Replace the Sunroof Motor (if needed)

If the motor is faulty, remove the sunroof assembly by unscrewing it from the roof.
Disconnect the old motor from the assembly.
Install the new motor by connecting it and securing it back into place.
Reinstall the sunroof assembly and ensure everything is fastened correctly.
