What goes wrong
Over time, debris like leaves, dirt, and pollen can accumulate in the sunroof drainage tubes, obstructing the flow of water. When it rains or during a car wash, the water can't exit through the drains and instead overflows into the vehicle's headliner, A-pillars, or even the footwells. This can lead to damp carpets, stained headliners, and in severe cases, damage to electrical components or mold growth.
Symptoms to watch for
- Water dripping from the headliner or A-pillars
- Damp carpets, especially in the front footwells
- Musty odor inside the vehicle
- Visible water stains on the headliner
- Malfunctioning electrical components (e.g., dome lights, infotainment)
Root cause
Accumulation of debris (leaves, dirt, pollen) in the sunroof drainage tubes, preventing proper water drainage.
Permanent fix
- Regularly clear sunroof drain tubes of debris
- Inspect drain tubes for kinks or disconnections
