Water leak under rear lights

I've a 98 model and recently removed the ply lining kit. I've noticed that in the cargo area under both rear lights there is a pool of water on nearside and offside. You have to put your hand in the small hole in the corner where the lower nut is that holds the rear light. I've no idea where it's coming from. Has anybody else experienced this and know where the water is getting in?

Most likely the rubber seals on the tops of the rear doors are not doing their job. I've a similar problem with the sliding door seals on my van. I haven't tried to fix mine yet but maybe instead of replacing your seals if they're in reasonable condition, you could adjust the hinges so they pull the doors in a bit tighter to the body?

Could just drill a small hole so the water drains away

Re: Water leak under rear lights

Since posting, ive removed the rear door seals and cleaned them up. They were full of crud. They have came up like new. I think you are spot on Steo as there was a small hole behind one of the seals. This has now been filled and seems to have done the trick. Thankfully there are grommets to drain the water. There must have been a pint in each corner for a few years at least. No rust whatsoever. Glad it wasn't a Ford

Thanks for the feedback & great to hear it was an enough easy fix.

Mine was leaking at the tail light seals. Look at the floor in the section when you loosen the lights as well. I cures mine with dome D shaped door windo seals from ebay

I've just found another water ingress point that allows the rear light void to fill up.
It's the top corner, where the roof meets the sides and the pillar for the door. This corner (on my van, at least) had some hard mastic seam sealer applied at manufacture (because it was covered in the vehicle paint). The mastic, over time, has cracked and was allowing water in with a good amount of capillary action.
I've cleared out all the mastic down to bare metal (heat gun and a scraper) and have temporarily applied some waterproof tape all around to see if I've located all the problem. If so then I'll apply some silkofix and keep my fingers crossed.
