Yes, a clogged sunroof drain tube can cause water leakage into the car. Here are some details about clogged sunroof drain tubes: 1. Check the drain holes: If you find that the sunroof is leaking, the first thing to do is to check the sunroof's drain holes to see if they are clogged. Parking the vehicle under trees by the roadside can easily lead to clogged drain holes due to fallen leaves, resulting in sunroof leakage. Sunroof leakage is caused by blocked drain holes, and timely unclogging of the drain holes can resolve the leakage issue. 2. Inspect the sealing strips: If the sunroof's sealing strips are damaged, it can easily cause accumulated water on the roof to seep in, leading to sunroof leakage. Timely replacement of the sunroof sealing strips can prevent leakage.
I've been driving for over a decade, but got badly screwed by clogged sunroof drainage pipes. I remember one time after a heavy rain, found the passenger foot mat completely soaked, lifting the carpet revealed a pool of water underneath. Inspection showed the drainage pipe was completely blocked by leaves, causing water to backflow into the cabin. Later spent over 800 bucks on repairs - not only had to unclog the pipes but also remove seats to dry the flooring. Learned my lesson now - every quarter I use a bicycle pump to blow air through the drainage outlets a few times, especially for cars parked under trees in summer. Grit in the sunroof tracks also needs regular cleaning, otherwise the cabin turns into an aquarium in seconds when clogged.
