All,
I bought a Mondeo (1.8 TD Diesel, 1999 model) this summer, and in the last few weeks (since it started raining) have discovered that there is a lot of water in the boot of the car. This has travelled onto the back seat of the car - which is now constantly wet as a result. In fact, in the sunken housing where the spare tyre sits, I found literally 4 inches of water when I then extracted using as mug.
Does anyone else have this problem - what is the likely cause? Maybe the seal around the rear windscreen? Maybe the tail lights? Apologies for the naive questions!
Many thanks in advance.

Oh dear - last time I saw this it was because the car had been damaged in an accident. The previous owner had reversed into a bollard and although it had been fixed, the seal on the boot was never the same.
Every time it rained, the water flowing off the roof & rear window would go into the boot instead of around the seals. I assumed the the boot & surroundings weren't quite the same shape, so there was a gap in the seal.
Never did fix it. I passed the car on and last I knew the next owner blew it up driving it across Eastern Europe.

My brothers Mondeo had the same problem. The water was coming in at the point where the windscreen wiper was attached to the car. It hadn't been put on properly so the seal wasn't working. 20 minutes after discovering this the problem was solved!

Previous posts have mentioned that water can get in through the light clusters. Remove rear lights, smear with silicone rubber sealant and replace.

Strange how that is an old ford problem.I would have thought it would have been sorted by now.

Had the same problem with my Mondeo,read the notes that HJ had posted on the Car By Car Breakdown re rear light clusters.
Removed the clusters,removed the old damaged seal and replaced with new.
Several months later,all appears to be ok.

Where did you get the new seals from?
Ford are adamant that they don't sell replacement seals.
The boot on my Mondeo leaked, silicon sealant did the trick perfectly!
I think the boot seal does 'relax' over time as the boot lid was rattling on my car after 50,000 miles or so. No water came in though and I just adjusted the boot latch to stop the rattle.

Same experience as me. Just left the old faulty seal in place, ran a bead of silicon round and all is well after 12 months. Needed quite a shove from inside the boot to get the clusters off, as it looks like the factory seals are applied wet and bond to the body.
Nothing to worry about, it's an easy job

ps.!
I also punched holes in the plugs in the bottom of the spare wheel well, to drain out water, should any collect in future. It might be sensible for you to do the same.

Well, well, it's this old chestnut yet again!
Yes, almost certain that water ingress is via the rear lamp cluster seals.
Yes, quite correct, Ford do NOT sell the seals, only new lamp clusters at about £56 each, last time that I asked. I would be very interested to know, perhaps someone might be able to tell me, whether Ford have changed the type of seal on the replacement units; I understand from speaking to the chap in the spares counter that cluster units are supplied new complete with seals.
Ford are WELL AWARE of this problem, it occurs so often, but they just don't want to know, even when affected vehicles are covered by their so called "warranty".
The cure, as already stated, is to remove each cluster, apply a thick bead of silicone sealer to the existing seal, allow to set for a couple of minutes, and then refit cluster and retaining nuts. Do not wash the cluster while it's removed because it is nearly impossible to get the water out from the various internal layers afterwards.
Some might say to remove the existing seal first. I didn't do this as it would mean having to apply a very think bead of sealer, and I'm not sure it would be possible to do this using a standard type of mastic gun. Could do it in a couple of separate applications, I suppose.
In my own case the "cure" has worked, well, so far, anyway!
Good Luck!
