Whenever it rains hard for a prolonged period the passenger side rear seat gets flooded!!

What's up with that? Is that normal and I'm just going to have to live with it?
Is there possibly a drain tube that is blocked under neath the tonneau cover?

 

No, the flooding is NOT normal. Do you own a convertible or coupe.

If you own a convertible, are you saying that top leaks?

Provide a better description of your problem and car MY so we may lend some assistance to you.

 

Yes. It's a 2008 XKR Convertible. I was speaking with 1 of the parts jockeys at the dealership and he suggested that I may need to replace the top.... NOT GOING TO HAPPEN for a simple leak. He did show me where the glass was separating away from the canvas...but I think that I can reseal that with some mirror epoxy adhesive.

 

There is a thread on convertible top repair. It has the TSB in it. I'd send it but I'm using my phone. Some say the repair lasts a long time.

Luckily the XK top sort of lifts up in the back when you start to open it, so you can easily clamp some wood onto the repaired area until it has time to cure!
