Hi all and happy new year today pulled passenger seat belt out and it was wet door seals all look good seams to be in channel were seat belt fitted any one had this before took shelf down above sliding door can't see were it's coming from?

Had it once or twice, also occasionally get same on car, no idea why. If it was regular , I'd search for reason but its so occasional I just put up with it.

It’s condensation in between the panels

Had a look with endoscope when it was raining water may be come in from awing light fitting screws or were wiring comes in will have a look when we get heavy rain

Update on leak took shelf down above sliding door and plastic door trim around passenger door and seat belt leak is coming from seam in roof were they seal panels together looks ok outside must be going pourous with age

Are you able to fully clean the outside seam along its length, you could try something like this on the out side seam to seal , I used similar on the Autotrail roof on a join that was aged and would  have been a major job to resell , it solved the problem

I'm going to try trolleys creeping crack when it drys out and warms up used it on old caravan seamed to work well

Captain Tolley's Creeping Crack Cure works well on very small gaps, but not so good on wide ones. I would try both Tolley's and then tape over the gap.
