What to Do When the Car Sunroof Is Left Open and Gets Rained On?

First, close the sunroof immediately to prevent further damage. Once the weather clears, carefully inspect all areas of the vehicle that were exposed to rain. For parts that can be removed, disassemble and dry them thoroughly. For non-removable parts, ensure they are dried as quickly as possible to maintain the vehicle's normal operation in the future. Here are two key points for window maintenance: 1. Window Defogging: Slightly open the windows to allow air circulation between the inside and outside of the car, maintaining consistent temperatures to prevent condensation on the windshield. Turning on the air conditioning to adjust the cabin temperature can also help eliminate fog on the windshield. Additionally, applying a thin layer of glycerin, alcohol, or saline solution as an anti-fog agent can prevent short-term fogging on the inner surface of the windshield. 2. Electric Window Maintenance: Pay attention to the oil level in the door's internal lift mechanism to ensure smooth operation of the electric window switches. Dirty or damaged glass can also hinder movement, so it's important to keep the windows clean.
A few days ago, I forgot to close my car’s sunroof, and it turned into a swimming pool—what a painful lesson! Immediately remove the key and cut off the power—never turn it on! First, use towels to soak up the water pooling in the headliner, or it’ll leak even more. The key is to remove the seats and lift the carpets, otherwise, the soaked areas will mold. If you have the tools, you can extract the water from the carpets. Turn the AC to maximum heat and blast it—I had to air-dry mine for two full days. While at it, I cleared the drainage holes at the four corners of the sunroof with a thin wire, pulling out nothing but mud. Now I’ve bought a Bluetooth sunroof alarm—my phone alerts me when I leave the car. Oh, and after the rain stops, remember to re-stretch the headliner fabric, or it’ll sag and look awful.
Our shop frequently handles flood-damaged vehicles. Post-rainwater treatment follows five steps: First, avoid powering up at the scene. Second, extract water from carpets (check the spare tire well in the trunk too). Third, remove seats and sun-dry the frames. Fourth, focus on electrical inspections—seatbelt pretensioners and dome light modules are most vulnerable to moisture. Finally, perform full-vehicle ozone deodorization. For DIY treatment, you'll need to place an industrial dehumidifier inside the car and run it continuously for three days. The soundproofing felt beneath the carpets must be replaced, otherwise, the sour stench next summer could be overwhelming. We recommend performing sunroof track maintenance while you're at it, as rainwater can cause rubber seals to deform and leak air.
