Water leak on driver and passenger floor

Postby cedriccools » Tue Sep 19, 2017 2:09 pm

Hi guys

I am currently fixing all problema on the 1989 4.0 xj40 i recently bought.

One of them is there is water leaking in near the fuse boxes on both sides. It looks like someone is holding a bottle upside down.

I notices the cover over the swipers wasnt fixed, and there is a lot of mud underneath. I also found out the frontscreen was wet. There also comes water in the gap underneath the swiper.

I have been looking for some water canals ii read, but cant find them.

Any thoughts on where to look? The left air blower fan inside is also blown every time, maybe the 2 are linked?

In one pic there you can see water sitting inside the plenum chamber. You need to remove the Duck bill/ rubber baffle that sits below the wiper motor housing. Hard to see with so much gibbons on the way, but remove the battery to allow better access.

If that doesn't work, you may need to remove the wings to loom for rust holes behind them. All the water that flows down the roof gutter goes under the wings and can rust through, hidden from view.

found the duckbill yesterday, and indeed, full of sand and dirt. cleaned it out and flows away now. I have already been searching but can't find a frontscreen rubber. is there a shop you advice? or is this a part that can't be supplied new?

Taking into account your chassis number the screen surround rubber would be BEC25260, no longer available from JCP so you may have a search on your hands.

If you remove the rubber carefully it can be reused.
The windscreen is bonded in, not held in place by the rubber.

I know this is the case for later MYs (my windscreen has been out for a new headlining, we reused the rubber when it went back in), can someone with more knowledge of the older model years confirm this?

I tried to remove the windscreen rubber from the Gold I stripped without success, it was stuck in fast and tore as I pulled it out. I suppose it depends on wether the mastic has stuck to it but yes you may be able to remove one without damage.

I don't think changing the screen rubber will necessary be beneficial to the water leak issue. As mentioned, the screen is bonded in. That bonding is what keeps the water out. The rubber (with stainless trim) you see on the outside is just a finisher trim in reality.

Did you do a forum search on "water leaks into the footwell"?
