How to Service a Sunroof in a Ford Focus

If you properly maintain your Ford Focus's sunroof, you can enjoy the open air in good weather and eliminate leaks and squeaks. It's generally recommended you clean and inspect your Ford Focus's sunroof at least twice a year.

Access your sunroof by removing the interior trim work and headliner inside your Ford Focus.

Remove the screws and bolts that hold your sunroof to the top of your Ford Focus. Unplug the electrical power source, if your sunroof is electric. It's located at the rear of your sunroof.

Lift the sunroof up and away from the vehicle. Set it aside in a safe location.

Take the old rubber seal out of its channel. Use your plastic scraping tool to remove stubborn rubber or any adhesive that remains. Inspect the channel for rust. If you see any, paint the channel with Rustoleum to prevent further deterioration.

Install the new rubber seal in the channel, outer lip first and then the inner lip. Inspect the seal for bulges wrinkles. If you find any, lift the seal at that location and reinstall it. Keep doing this until the seal is seated smoothly inside the channel.

Install the sunroof back into your Ford Focus and secure it into place using the screws and bolts you removed earlier. Stop and check frequently to make sure it's level, and don't forget to plug the sunroof back into its power source. Replace the headliner and trim pieces.

Inspect the exterior of your sunroof of your Ford Focus 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 Ford Focus. 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 Ford Focus's sunroof 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 remove debris, then lubricate the tracks with 3-In-One.

Lubricate and clean your rubber gasket. Wipe it off with a clean rag, then use the lubricant outlined in your owner's manual. If your seal is stiff or show signs of excessive wear, replace it so your sunroof doesn't leak.


Never use WD-40 to lubricate the tracks on your sun roof, as it's water based and will cause damage and leaking. Contact your dealer if you have difficulty with your sunroof assembly. There is a technical service bulletin for this problem, most commonly reported in 2002 model years. A technical service bulletin is not a recall. Unless your vehicle is under warranty, you will be charged for any repairs made to your Ford Focus sun roof.
