Hi there, I bought a Volvo a few months ago 2005 V50. The car is great. There is only one problem, during a heavy rainfall the sunroof leaks and there is a lot of water on the driver side floor mat. One day I opened the sunroof and pour some water into the drains to check them and the water was dripping slowly under the car. What do you think ? Maybe clogged a little so with a big amount of water the water start coming back? What is the best solution for that problem?
Thanks

 

Found the problem. I had to clean all drains. No more water on the floor

 

How does a person locate the drain lines/ # of them, and then how can I clean them?!?

 

This is what I did:

First I took out the A-pillar ( make sure there is no airbag ) so I can see the drain lines. I poured some water into the holes in the sunroof to see how slow the water drained. Then I took out the inner wheel arch and located the drain with ankle. This ankle was the problem. It was all clogged. I just cleaned it and now have no problem since time.

Good luck.

 

Thanks...now to figure how to remove a-pillar....lol

 

Try to search "Retailer Technical Journal 14545" on the web. It shows where the leak could be.

 

I appreciate your suggestion. Thank you.

 

Same happened to me, left the car outside one night with a lot of rainfall, got into the car the next morning and had a pool party.
