How to Service a Sun Roof in a Lincoln Navigator

by Contributor

If you properly maintain your Lincoln Navigator's sun roof, you can enjoy the open air in good weather and eliminate leaks and squeaks. It's generally recommended you clean and inspect your sun roof's rubber seals at least twice a year.

Replace the Gasket

Remove the interior trim work and the headliner cloth that cover the top of your Lincoln Navigator.

Unscrew the screws and bolts that hold the sun roof to the Lincoln Navigator. Unplug the electrical power source from the rear of your sun roof.

Lift the sun roof off the Navigator. You may need the help of another person to perform this action without damaging the sun roof or the Navigator.

Pull the old rubber seal out of the trench where it rests. Use your plastic scraper to remove any excess rubber or adhesive from the trench. Also check the trench for signs of rust and coat it with Rustoleum if needed.

Lay the new rubber seal in the trench. Start with the outer lip, then move to the inner lip. Check for ridges or wrinkles. Remove the seal in the spots where it doesn't seat right and reinstall it so the seal rests evenly and smoothly inside the trench.

Return the sun roof to its normal position and secure it to the frame. Check often to make sure it's level, and don't forget to reconnect the power to your sun roof.

Place the headliner back into position, followed by the interior trim work.

Maintain Your Sun Roof

Inspect the exterior of the sun roof of your Lincoln Navigator on a monthly basis. Look to make sure it's evenly seated, not lifting at one corner. Lifting indicates it's time to clean and lubricate the tracks.

Check the draining tubes for your Lincoln Navigator. Two drain to the front of your vehicle, typically beneath the fenders. The other two drain to the rear of your vehicle, usually behind your tail lights. Use compressed air to blow out any debris, dust or clogs.

Access the tracks and seals of your Lincoln Navigator's sun roof by removing the interior trim and letting the roof cover drop. You don't need to completely remove it, just let it hang. Use compressed air to blow out debris, then treat the tracks with 3-In-One lubricant.

Lubricate and clean your rubber gaskets. Wipe them off with a clean rag, then use the lubricant outlined in your owner's manual. If your seals are stiff or show signs of excessive wear, it's time to replace them.

Warning

  • Never use WD-40 to lubricate the tracks on your sun roof, as it's water based and will cause damage and leaking.
