Hello,
I noticed water inside my H2 (under carpets, and also under the plastic part under the door), which has been partially solved by replacing all roof lights (some were damaged with time) and also fixing the related potential water leaks with some sealant around bulb cables.
I still need to clean the sunroof drains to ensure they are not clogged, this will happen as soon as we have some few days without rain.
But I stil have some condensation on the inside of the sunroff glass, and for this I have absolutely no idea why it happens.
any idea will be more than welcome,
Thanks in advance,
Leto.

 

It is telling you that you have water inside the cab.

It can take many months AFTER all leaks are fixed to dry out carpet underlay, and you risk rusting out the floor pans. You need to lift and dry carpeting.

After all leaks are fixed, place dehumidifier(s) in vehicle for a week or so, and see what you catch.

If you live in a maritime climate with moist air, the process can take 6x as long as for those living in Arizona.

 

Hi finall,
many thanks for your advice. I already had leaks under the driver's carpet. I suppose leaks from the sunroof. I will try to clean those and see.
i'm afraid drains are clugged in some ways.
I live in France, where it rains more often than Arizona I guess
