How to Repair (Part 2)

2.1 Drain Tubes.

There are only two drain tubes fitted to each sunroof. These are all towards the front and operate to some extent independently. The rear sun roof drain tubes exit near the rear lights and on the front they disappear down the ‘A’ posts by the windscreen. (On the Land Rover Discovery)

You need to ensure:

3. Rubber Seal.

This is an easy item to change if you can get hold of one. It appears only to be sold as part of the sunroof assembly? However, I have seen them for sale separately on e-Bay.

But before you go down this route and spend hard earned cash; is it the seal causing the problem? It should only be the cause of the problem if it is dirty, damaged, or has an inherent defect? This should normally be visible.

The root cause of water ingress in a sun roof is often via:

To remove the seal, simply open the sun roof and pull it out of the recess.

Note that you may see water on the seals from condensation running off the glass sun roof, or water running in from outside when the window opens.

Testing

You can test for leaks by pouring water into the drainage ‘drip trays’ and watching for water running out under the car. Note that:

To check the overall water integrity of the car (for the sunroof), you may need to leave the car parked in the rain for a day. Note that the most efficient way of testing is to park the vehicle on a slight slope. You may need to try both nose up or down? (Take note if your vehicle tends to leak more when parked in a particular position?).
