If it had been a sunroof on a tin top ,it could have been the drain tubes.

Hi,

Did anyone come to a conclusion in regards to the leaking sill mystery.

I too have found my sills leaking last week. It's not the rear heating system as that is isolated and drained.

Any findings will be appreciated.

Thanks in advance

I'm not sure this isn't just normal drainage.

I had a similar thing happen but the water ended up on the inside where the heater unit was (removed), the aerial was the first suspect but was found to be OK, the other thing that was checked was the door switch, this was dry too.
Final conclusion was for it to be condensation, a lot of water had miraculously formed inside, enough to fill a cup in a matter of days.
The best thing to do would be to use a dehumidifier inside the van for a few days, keep the van cool thereafter and see if it happens again, if so, you have a leak.
