Water collecting on twin slider bottom channel

When it rains and I open the sliding doors, loads of water comes flooding out of the channel the bottom slider sits in is this normal? If I don’t open the doors it will sit there till I do
 
I am not “the authority” on declaring if this is normal or not, but I have never had water run out of any part of the sliding door or its bottom rail.

I can’t quite imagine how it gets in there but it doesn’t sound right to me.
 
Yep mine does the same, my drive is on a slope with the front end lower than the rear, I thought it was normal lol
 
My drive slopes, van parked nose down and never had any water come out of the sliding door!

VW OEM sliding windows - they’re another matter though since cleaning the rubbers and applying Autoglym vinyl and rubber seem ok.

I didn’t think it was right it’s like a river comes flowing out as soon as the doors opened it’s trapped in the sliding channel till the doors relised

Thankfully iv never had any issues regarding the sliding windows
 
I have the same problem and am wondering if the door seal around the bottom is causing the problem. There’s no drain holes in the channel, unlike earlier versions of the van. But surely the outer door seal [this one on door and not the ‘main seal’ on the van aperture] is preventing water draining out of the underside of the door by trapping it and is also diverting water to fill up the channel. Premature failure of the slider roller has just drawn my attention to this issue- the bearings got rusty and disintegrated.

I am wondering whether to remove the bottom portion of this seal.

Same on mine. What did you do at the end?
 
Yes, I cut away / removed the bottom section on the door seal. I think I’ve also put another thread about this. It’s worked brilliantly for me - when I get a chance I’ll post a photo. IMHO it’s a design flaw- the outer seal traps the water which is also why it sometimes gushes out when you open the door after rain.

Aha, ok. Mine is on a sloping drive (van leaning on the driver's side slightly) and the passenger side is higher hence water collection in the roller wheel housing, it's like a mini aquarium to be honest. So I periodically collect it with a small towel and dry it that way. Crazy design, just can't work out how the water even gets in? I know it's leaning, but surely this shouldn't happen.

Follow the links I posted on the other thread you asked this on for some ideas.

Regardless of how it's getting in you need to get it out, mopping out occasionally is not going to stop your bottom roller arm components corroding.

I have also removed the bottom rubber, but not sure will this work?

To the front where I am pointing with my finger, I reckon that where the water is coming in, it almost needs a small seal to close this gap. I tried to place a small piece of high density foam, but it's not staying there. I managed to close/wedge the other gap to the right side (other end). The last photo is with the bottom rubber removed.

If there is no water in the pocket then you're good.

I didn't go as far as removing it as it should be protecting from road spray so I just put some wedges in at the low point to ensure it drained.

I also regularly dress the seals with seal grease to ensure the best possible seal, tops around all doors and the very fickle tailgate seal.

I use the Honda Shin Etsy grease mentioned on this thread, not cheap but I expect it will last many years as so little is needed:


If you haven't already double check your sliding window seals (if fitted) and the handle (if it's straightforward to get the panels off) as most likely entry points in the door itself:

Same here with Shin Etsu grease, had it since the tailgate rubber leaked 2yrs ago which solved the leaks, so always use it from now on, and on all door seals to keep then nice an plump.

We had rather heavy rain here in mid Wales for the last couple of days, and there was lots of water this morning, small puddle right at the end where the small wheel stops. I dried it Sprayed some silicone rust protector just in case and then decided to remove the bottom rubber seal, but this is where I am puzzled will it work with the rubber seal being removed now?
