What to Do When the Cabin Roof Leaks?
2 Answers
If the amount of water entering is very small and the wetted area is minimal, simply wipe the water stains clean yourself and lower the car windows. If the amount of water entering is substantial, inspect other areas that may have been soaked by water. Address the locations where water has entered. Have the vehicle towed to a 4S shop or repair shop. Observe the vehicle repair process.
I often encounter this situation during the rainy season. The most common cause of water leakage from the top of the cabin is a clogged sunroof drain hole. Rainwater accumulates in the sunroof tracks and then seeps into the car through the headliner. You need to quickly use a thin wire to clear the drain holes, which are located at the four corners of the sunroof. If the drain pipes are completely blocked by mud or sand, you might even need to remove the headliner for cleaning. Also, check if the roof sealing strips have aged or cracked, especially in older cars, as deformed rubber can no longer keep water out. I’ve also seen cases where water leaked through the screw holes of roof racks, which requires resealing with adhesive. A word of caution: if leaks aren’t addressed promptly, they can corrode wiring. The worst-case scenario is water dripping onto the airbag module—that’s a real headache.
