How to Unclog a Blocked Car Sunroof?

Take an air pump gun, aim it at the drainage holes of the two front drainage pipes inside the sunroof, and use high-pressure airflow to blow through the drainage pipes. Using a syringe to flush the drainage pipes should be able to clear them.
Last time I dealt with a clogged sunroof, I did it myself. Open the sunroof to check if the drainage holes are blocked by leaves or debris, and use small tweezers or a vacuum cleaner to clean them first. Then take a bottle of mineral water, pour some water into the drainage holes, and test the flow. If the water doesn’t flow smoothly, use a thin plastic drain snake or a soft hose to gently clear the blockage—never use hard wire as it can scratch the rubber tube. After finishing, pour another cup of water to test if it drains properly. Finally, remember to wipe dry any water stains on the tracks to prevent rust. It’s best to check the sunroof tracks every month, and parking away from under trees can help reduce clogging issues.
I recommend preparing some common tools to deal with a clogged sunroof. First, use a flashlight to locate the drainage holes at the four corners of the sunroof, and clean the dust and debris in the tracks with a brush. If the drainage holes are clogged, you can try flushing them with a hose or blowing out the debris with compressed air. If you can't find the right tools, a thin wire wrapped with a cloth can also work as a temporary solution. It's important to check if the drainage pipe outlet under the windshield is also clogged, as this area is most prone to accumulating leaves. Finally, remember to inspect the sunroof's sealing strip for any signs of aging. Poor sealing makes it easier for debris to enter and cause blockages, so replace it if necessary.
