Water dripping from the headliner after a storm, or a sunroof that refuses to close with rain in the forecast. Both feel like emergencies, but in most cases the fix is smaller than you think.
The four most common sunroof problems
Water leaks
Usually a clogged drain tube, not the glass. Water backs up in the tray and finds its way into the cabin.
Stuck or off-track
Debris in the rails, a worn cable, or a panel that has jumped its guides. It jams partway open or closed.
Shattered glass
A rock or temperature stress can break the panel. Tempered glass crumbles all at once, like a rear window.
Worn seal
Rubber hardens with age and Quebec winters. A tired seal whistles on the highway and lets fine dust and moisture in.
A leak is usually a drain problem
Most sunroofs are designed to let a little water past the seal on purpose. That water lands in a tray under the glass and exits through small drain tubes running down the pillars. When those tubes clog with leaves, pollen, or road grit, the tray overflows and the ceiling drips. The seal gets blamed, but the drains are the real culprit in a large share of the leaks we see.
Pour a small cup of water into the open sunroof tray corners. If it does not appear under the car within a minute or two, the drains on that side are likely blocked.

Why waiting costs more
Water that keeps finding its way inside does not just stain the headliner. It reaches wiring, airbag sensors and modules that live behind the trim, and it feeds mold in the carpet padding. Depending on your policy, water damage claims can also get complicated: Infoinsurance, the reference site of Quebec insurers, explains how water related coverage works. A drain cleaning or a seal replacement today is always simpler than an electrical diagnosis in three months.
