Repair Instructions

Step 1: Remove the Sunroof Panel (if necessary)

Disconnect the Battery:
- Safety first! Disconnect the negative terminal of the battery.
Remove the Headliner:
- Carefully detach the headliner from the edges to access the sunroof mechanism. Use a flat-head screwdriver to gently pry it away if it’s clipped in.
Unclip or Unscrew the Sunroof Assembly:
- If required, remove any screws or clips holding the sunroof assembly in place. Typically, this involves removing four to six screws using a Phillips screwdriver.
Lift Out the Sunroof Panel:

Step 2: Inspect and Clean the Sunroof Seal

Examine the Seal:

Clean the Seal:
- Use a soft cloth and a mild detergent to clean the seal and the area around the sunroof. Ensure all debris and old sealant are removed.

Step 3: Clear the Drainage System

Locate Drain Holes:
- Identify the four drain holes located at each corner of the sunroof frame.
Clear Any Blockages:
- Use a vacuum or compressed air to remove any debris from the drain holes.
- If using compressed air, be cautious not to damage the tubing.
Check Drainage:
- Pour a small amount of water into the sunroof channels and ensure that it drains out of the holes underneath the vehicle.

Step 4: Seal Any Gaps

Apply Silicone Sealant:
- If the sunroof seal is damaged, apply a silicone sealant to any gaps or cracks in the seal. Ensure it is designed for automotive use.
Reinstall the Sunroof:
- Position the sunroof panel back into its place and secure it with screws or clips.

Step 5: Reassemble the Headliner

Reattach the Headliner:
- Gently press the headliner back into place, ensuring it is properly aligned and secured.
Reconnect the Battery:
- Reconnect the negative terminal of the battery.

Final Step: Test the Repair

Conduct a Water Test:
- Close the sunroof and pour water over it again. Check for any leaks into the cabin.
Observe for Improvement:
