- Where Are The Water Leaks On The Lexus Coming From? I'm struggling to find the cause of water ingress on my LS400, is it the screen? Sunroof drains? Or a door seal? plus the boot seal is also leaking.
Best way to test windshield is to put some cleaning foam on the outside and using compressed air from interior side to blow along the sides, if foam starts to bubble you know you have a leak. 😄
clever
I wouldn't even hesitate to get your mate to whip the screen out and completely rebond it. My guess is that the shock of the impact from the incident that required the fitment of the new drivers door also disturbed the substandard bonding on the replacement screen - coupled with possible shrinkage with the extreme temperature differences the car has endured travelling from the UK over to Spain in recent years making the bond even more brittle and prone to leakage.
Completely agree with you.
100% agree
Yes but that will probably cost a new screen as the old one will probably crack coming out.
@@richfixescarsA skilled fitter can easily cut that out especially if the bonding is poor. At my old works we had bonded screens carefully cut out and refitted from all sorts of rare exotica with replacements unobtainable or on long back order from pilkingtons when cars came in for full bare metal restoration or repaints.
Remember the old Seek and Seal adhesive in the seventies that I used on a number of cars with poorly fitted windscreens . I do feel your pain !!!
Cheers Jack, merry christmas. Gives a new meaning to dry January.
Happy Christmas Jack. Thank you for all of the entertaining content throughout the year.
When my sons fiesta was letting in water, I bought a cheap smoke machine and used that to see the smoke coming out of a few gaps.
My W210 estate manages to have a leaky roof without a sunroof, if you brake hard after rain it drops water out of the interior light at the front so it must be getting through the screen seal or the antenna at the back which seems unlikely. Old cars are so much fun to daily....
Hi Number27 !!!...... (i think i have the answer lol).....(and it's so easy)
...
Give the lovely old car a wash .... and just place a small heater inside to dry the moisture !!!
...
Then add some silicone dehumidifiers from a cheap shop and now here's the trick !!!
...
When the weather is cold and dry ... just give the "old girl" a polish with some "turtle wax" including the door jams and the troff where the water gathers by the boot seal and sunroof !!!
...
The rain water will turn into beads and just roll to the floor !!!
...
Then drive the car with the heating on "full blast" and then open the windows !!!
...
(YES) .. it will still leak slightly but not like a "moldy greenhouse" lol !!!
...
Dont forget to spray some "dash shine" on the velvet seal of the sunroof !!!!
...
HAPPY CHRISTMAS AND LEXUS MOTORING !!!.....(even polish under the bonnet .. every bit will help)
The ONLY real fix is to remove the windshield and have it resealed (or replaced if it breaks while being removed)! Good Luck...
I can feel your pain, I have a similar problem with my Honda CRV, its driving me round the bend . May I wish you and yours all the best for the future and have a wonderful Christmas
How old is your CRV?

@@otsef1946 👍age, heat etc are factors that make a sealant to fail. I had the same issue with a 2001 civic.
@@ruinunes8251 I agree with you and thank you for your interest in my old banger. I am trying to reach 200 thousand miles, I am at 180 thousand
The Philips screws may actually be JIS (Japanese Industrial Standard). They look almost identical, but they're not, and a normal PH screwdriver tends to mess them up.
Nice detective work, very logical. Have a very Merry Christmas.
Great Video, look forward to seeing it fixed. The LS400 is a great car.
I approve of this content. Also noticed that the steering wheel in your LS400 looks great whereas I have never seen one in an LS460 or LS600h that wasn't really worn. This car was either really well cared for or the quality of the leather on Lexus steering wheels has gone downhill (or both).
Try some 'Captain Tolley’s Creeping Crack Cure' it was made for fixing leaks on boats and worked on the rear screen of a Rover 75 I had.
Jack, the Lexus wants you to move to a sunny dry climate 😉
Merry Christmas to you too Jack, try and have some time away from the cars!
Good result, look forward to the next one 👏🙂
Merry Christmas Jack!
Did you consider trying a smoke machine in the car to find the leaks, they work well, think they used one on wheeler dealers once on an Aston, seem to do the trick.
I have had two Ls400,s and E38 7 series the BMW was a money pit
On all these old car channels it is the mistaken view that Toyota/Lexus are magical products. But they are mass-produced cars built with profit in mind. I was disappointed with my nearly-new LS430 in the day that had component and assembly faults. The XJ Jaguars I have had since had fewer faults, classier interiors with quality materials and were much better to drive.
Happy Xmas Jack enjoy your videos but still not sure about the crap mobile aka bismerk I'm not a fan of German cars 👎👎😁😁
Just check that the sunroof drain tubes are clear
He went over this in a previous video, THEY ARE CLEAR!!
Regarding the screws I’m not sure if you are aware but the Japanese have their own take on the Philips screw, the Japanese use their own version called J.I.S ( Japanese industrial standard) you may need to ask Father Christmas for a set 😉
I was thinking the a normal Philip's ph2 will always camout in Japanese car's use a jis2 screwdriver.
I spent 25 years of my working career repairing water leaks in cars. Don’t remove the windscreen to repair one tiny leak and don’t use silicone as others have advised. Get some proper glass sealant from your auto glass friend. If a vehicle has been in an accident the shock is transferred throughout the car and body seams open up. Even a tiny hairline crack will allow gallons of water to leak in by capillary action. Use compressed air blown from inside around the windshield and other body seams and soapy water on the outside will pinpoint your leaks. Remember too that water can be driven in forceably while the car is in motion. Door and boot weatherstrips rarely leak except if they are noticeably damaged. Good luck!
i was just thinking i wouldn't remove the windscreen for that leak either
@@raycroal
And why not ? It obviously was badly installed ! With the proper tools and experience, it's a one hour job for a competent worker ! It happens very often.
The first thing I thought of when you said you already checked the drains was if that is an aftermarket windscreen. I've seen several poor installations over the years cause severe damage. Glad you caught it before it got worse 👍
have you tried pouring water INTO the sunroof drains with sunroof OPEN to see if the water exits from the bottom of the car ? thats a GOOD way to find out, a visual look isn`t enough..............
I'd highly reccommend that when you get the leak sorted, you buy some reusable dehumidifier bags and stick them in the car and recharge in the microwave once a week or so, otherwise the car will be moist and humid for years. I sorted a leak in mine and I cleared up all the excess moisture in the air (and carpets, fabrics etc.) in a few weeks with a couple of 350g bags.
2 more ideas. One idea could be leaving a proper dehumidifier inside the car for a few nights or every single time he is not using the car. A dehumidifier bag never will beat the proper mains powered dehumidifier on full blast.
Second idea is taking the seats off, take the floor carpet off and give it a proper wash. After all this time with that moisture in the carpet, it will smell. Nothing beats the nice smell of fresh clean carpet.
@@ruinunes8251 For sure, that's definitely the more pro approach
I fitted screens for 9 years
I would remove and refit the screen, I'd say the issue is rust on the aperture at the top and the polyurethane sealant isn't stuck to the metal any more
The screen is an integral part of the structure of the car
Noooo, don't go near it with silicone, it won't stop anything and will only make things worse long term. As you have a friend that's a windscreen fitter ask him nicely to remove the screen for you. You might find a rusty seam has caused the bond to let go allowing water in. He really won't thank you if you use silicone, you can't bond windscreens back in over silicone.
Yep, it's gotta come out.
Yep, you are right. It happened to me a few years ago. I had rust just right under the windscreen sealant and was letting water in. Another car, the rust under the sealant formed a bubble and cracked the windscreen. For a while I was puzzled why one morning the windscreen showed cracked. Just when we changed the windscreen we figured out the rust bubble was the cause. I guess I’m cursed regarding windscreen
Let’s hope that’s the only leak......great video & happy Christmas 🍻🍻
With the screen Jack I’d get a professional to take a look bud, I’m sure you already know the windscreen is a structural part….. safety first ! Happy Christmas buddy 🎄
Please, please don't go down the Carwow route of gormless mouth wide open photos for your video thumbnails!
That's a long way beneath you....
Had a similar problem with a BMW the problem was the sunroof drain pipe was leaking inside the pillar with a crack in it when l put a new tube in it solved the problem.
Its not a troublesome car, its what they call OLD !!!!!!!👍👍👍👍
Can’t imagine why driving the Merc is embarrassing….😂😂😂
Get a windscreen company to come out to completely remove the windscreen and completely reseal it for all it costs it's not worth half arseing it and doing a bodge job
Having done some windscreen fitting in the past I'd say cut it out and rebond it. If I still had all the tools I'd do it for you but alas I don't.
I think it's had a prang and been repaired poorly hence the misaligned door, bent wing panel bracket and 3rd party poorly fitted windscreen. I think you were sold a lemon 🍋But have a very merry Xmas 🎄
That's what I was thinking, maybe the old man was a bit circumspect about the extent of the 'minor bump. There are some very un Lexus panel gaps on the nearside
Windscreens are a structural part of the car so removing and resealing the screen is definitely the way to go.
Such a lovely car. Bet it's a dream to drive. Screen out & clean up & re silicone. Merry Christmas 🎄
when are you going to show the smoothness of the running engine by placing a coin on top of it ????
🤝😎
I wouldn't recommend using silicon too on the boot seal, someone tried that on my LS400 before I got it and it didn't fix anything. Was a hassle to clean up silicon too. Much easier to replace the boot seal with one off ebay. Regular Car Reviews had a 2007 Honda Fit and it leaked in the boot and pretty much wrote that car off with the amount of silicon used to stop it leaking. The windscreen needs to be properly fitted on LS400s otherwise they leak as yours does and if unchecked will cause the A-pillars and roof line along the windscreen to rust.
Agreed, silicone is for bathrooms as it is acidic to kill the mold. Petroleum grease works great as it never dries and is also a rust inhibitor as it is hygroscopic. Apply liberally behind every rubber seal. A light coat on the sealing surfaces also keeps the doors from freezeling in cold weather.
Also, I believe Sikaflex is a better option than silicone on any metal surface as it does not contain acid.
@@olavstrand2491
Silkaflex is good but you'll never get the seal off again!!
@@markwalton8644 It’s not easy to remove, but not impossible using this method:
th-cam.com/video/NxXemzzyQZ4/w-d-xo.html
dont use sillycone....use SEAM SEALER!!!!!!
Love the tweeting birds sound track!!
I think your best bet is remove the windscreen have the area all cleaned and resealed best way
My first LS400 suffered from a poorly fitted replacement windscreen. It leaked in the centre of the dash. Numerous electrical issues. I drove south from Edinburgh in a 6 hour trip in worsening rain. I looked out at the car the following morning to see the wipers working even though the keys were in my pocket!
Water ingress had perished those large multi plugs causing numerous shorts... After repair I replaced the windscreen which revealed an extremely amateurish job from the previous job. A complete one foot section without glue...
Note: The button just below your drip .... I think it is audible chimes on/off.
Looking out to see your wipers working made me chuckle, a real wtf moment!
get your glass man to take the screen out and re-seal it!
Merry Christmas Jack! Please don't use silicone - if you do and it doesn't work then your windscreen fitter will really struggle to bond where the silicone has been..
Can't you get one of those smoke bomb things to set off in the car , then see where the smoke comes out.. just a thought.
Ha!! A bit radical…
I had a leak in my boot and found out it was a rubber grommet which was cut to route an after market reverse camera. I used gasket maker which is used to mate metal surfaces like oil pans to the engine and sealed up the cut grommet. My boot is bone dry now and has been for several years. Good luck
Thanks for sharing the tip. Merry Christmas
That bloody leak drove me nuts for a while as it is near impossible to trace.
But I DID !!!
Do you see how the plastic 'tongues' at the ends of the black plastic trim under the rear window has warped up with age ?
The boot lid acts like a remote fridge door light switch and when you close the lid it tilts the trim foreward and lifts its fixing plugs out of its fixings holes, thereby FUNNELING water in !
The Trim costs £500+ IF you can get one, so the simple solution is to remove it entirely and tape over those fixings holes as you can't see them OR the trim anyway when the boot is closed.
Job done ☑️

Happy Christmas Jack , great you’ve identified the source. Seems like a sound car that’s suffered from a sub standard windscreen fit.
One of my old cars had a leak from the windscreen, ended up having surface rust underneath the bonding which you couldn't see with the windscreen in. I would defo take the glass out.
Regarding the clocks, I'd sit them in the house in the warmth for a few days then plug them in and see if the light works.
Water leaks are cussed blighters. In the mid ‘90’s I was working for a Vauxhall main dealer, and sold a Calibra, which developed a water leak; the rear footwells were filling up after every rainfall. Ultimately, after several attempts at fixing the problem, our workshop had to strip the car of its entire interior, barring the driver’s seat, and one afternoon a mechanic drove the car through a local ford repeatedly whilst I lay on the bare floor of the car. The leak was eventually traced to a dislodged wiring grommet in the front bulkhead, which was allowing water to flow through to and settle in the rear floor of the car. Satisfying to solve, but very time consuming!
A SMOKE MACHINE (cheap on ebay) inside the car will show up the leaks in 10-15 minutes...... will be useful in the future too.
Easy peezy! Merry Christmas Jack from Rome🎄🎄👍🇬🇧
Merry Christmas Lad!!
Japanese cars and bikes don't have a single Philips screw on them. They have Japanese Industry Standard screws, which look similar but a Philips driver will often slip in them. If you don't have any yet, get yourself some JIS screwdrivers. Easiest available in UK is Vessel brand, often to be found on eBay UK.
I have come up with an exclusive 4-point action plan to fix your leaking luxo-barge issues:
1) pick up mobile phone.
2) Select contact to whom you sold Mercedes.
3) Dial
4) Grovel.
You're welcome.
Get it taken out and reseal 👍
Chris here from South Coast. I bought new a Lexus LS 400 around 1995. Brilliant car. Had it four years. Now retired and my latest car Lexus GS430 which I purchased 2 years ago and has sailed through 2 MOT's easily with only small service each time and one O2 sensor. Mileage just touching 45000 for a 2004 car. I love Lexus and enjoy your show on running repairs. Merry Christmas to you and Good luck with the channel next year.
3 thoughts, can you get UV sensitive water, would coloured water be a help? and aren't windscreens covered by insurance?
You still have an excess to pay. But if the only way to get rid of the water is changing the windscreen, better bite the bullet and pay the excess. 😃
Good job finding it!! And amazingly bad done windscreen, never heard of a leak THERE… Merry Xmas!!
Merry Christmas!!! from a new subscriber lured in by the Merc videos and loving the Lexus series (as a GS300 owner myself, with a one-time leaky sunroof...)
It's a big car with water ingress, why not call Sumo the driving Titanic as long as it leaks? My car has changed names from the "Exxon Valdez" to "Madame Dreyfus" (flickering eye). Guess what the first fault was.
Its really great you have found the problems with water ingress, and can't wait for the dashboard to illuminate again, great video, Merry Christmas, looking forward to 2022 and Number27 👌
Don't bodge it with silcone, remove the screen and rebond/reseal with the right product. Also if the sunroof drains are anything like Audi's where the plastic drain tube connects to the sunroof cassette they leak from there as the seal shrinks. Just pull the headliner back more and you will be able to see.
Seriously. I've never been so fascinated in water leak detection. Brilliant work Sir.
PS........HAPPY CHRISTMAS FRED !!! SEE YOU IN THE NEW YEAR
Going by the comments on here, getting your windscreen fitter mate to rebond the screen is an absolute no-brainer. The process would make for some decent content.
Windscreen A Piller, just like most Discovery 5’s! 😡. Rip windscreen out and put it back in!
Have you got any crack’s or chips on the windscreen to claim a new screen??
If I was you, I wouldn't waste my time screwing around with silicone. Just have the screen removed, clean everything up well, and let a glass profi reseal it and install it. I'm talking from experience here, it's really the best solution. And have a wonderful Christmas :-)
I would take the screen out. With the amount of water coming through, you may find the metal work underneath rusty!!
Good luck and Happy Christmas 🍻
Try using silicone spray lubricant on the rubber seals. It seemed to revitalise mine. Leaks can be difficult to locate. I had to get the windscreen resealed on one of my cars. Hope you get the leaks sorted. Cheers Paul 🍻.
Happy Christmas to you, glad you have tracked down the main source of the leak. 🎄🎅🏻👍
10/10 for perseverance Jack. I hate messing with dashboards and clusters.
Buy some cheap plastic trim tools for working on dashboards. It will not damage them like those screwdrivers will.
Once you have taken the instrument cluster out don't switch ignition on as it'll throw up an airbag fault and used to need dealer reset. Local auto electrical specialist got our LS dash fixed for £110, said solder joints go dry. clean sunroof drains out with curtain wire on the RX or 5mm strimmer on the LS.
You said the Bismerc was the only working car, what about the Elise?
From a fellow S1 owner.
Captain Tolley’s Creeping Crack Cure (genuinely the name!) is what I’d recommend… it sorted water ingress due to a cracked windscreen rubber on my race car.
Drains in windscreen are very usual in japanese cars.... sooner or later, toyotas, nissans and hondas will do this... the japanese "good quality" relies just on engines and electrics.... all the rest is "under standard"... corrosion... suspension bushings... steering... are just awful...
PS - I live in an island where it rains a lot... even more than UK...lol...
Nightmare of a water leak, I am glad it looks like you have answer. I once had a pollen filter cause me no end of grief, trying to diagnose it we had the window out twice and various other attempts until eventually we sorted the filter. Happy Xmas!
R+R the windshield is the only way to go. Hopefully the sunroof is ok.
Merry Christmas to you.
Maybe the sunroof drain is loose, disconnected, kinked it blocked lower down. Have you also checked the door drains in the bottom, not connected I know.Maybe scuttle drains.Get a tube of Tiger Seal and seal that half of the screen. Don’t take it out as that could open a whole can of worms.
Clean around the windscreen with brake cleaner, and a tooth brush. then use Black sticks all to bond around the window. It will outlive the car. Used it on many a Volvo it will cost 10 magic beans.
Merry Christmas Jack ! Those water leaks problems are the most annoying thing under the sun. Congrats on finding it 👍
playing with water in the cold is horrible.....isn't that what the garage is for....well done on your diagnostics...happy new year!
Check the plenum chamber and drain holes under the bonnet nearest the scuttle, I'm sure all cars have these ? .... Use a plumbers sink un-blocker to poke down into the tubes !!
A double-arm wiper! Of course, has Mister HubNut seen this video yet?
As I suspected, only way to fix it properly is get the screen taken out, look at the bond between the screen and the car, my bet is that when it was changed years ago they scratched the paint off the car back to bare metal taking the old screen out and bonded straight onto bare metal, over the years it’s rusted out that top corner and pushed the screen away then breaking the bond and causing the leak, screen out, sealant off, grind back, weld up and repair the windscreen surround (as it’s probably going to be holey), get it all painted, refit the screen, seen it loads over the years and very common on a lot of old cars.
I do prefer the videos where you are doing work on the cars. With your patience, you give me encouragement to try things myself. Paul
Definitely remove the screen and refit, silicone is to bodgy, Do the job right first time for piece of mind. Find a local reputable windscreen fitter!
All the very best Jack to you and yours to all the viewers stay safe folks and enjoy ,see you on the other side🥳 👍👨🏻🏭
Rain that falls on the sunroof and drops into the gutter around the sides and front of the sunroof opening, is drained by the pipes at the corners, and down the sides of the windscreen. There is no fixed gutter on the roof at the back of the sunroof, because the movable sunroof slides into the space that a gutter would need to occupy. Instead, there is usually a gutter fixed to the rear of the sliding portion, which collects any rain and diverts it to the side gutters, and down the corner drains. You should be easily able to remove the interior trim from the sunroof by pulling it downward, and when that is removed you will be able to see whether there is any corrosion in the moving drain which is allowing water to leak to places other than the gutters and drains. .Sunroof removal and refitting is pretty easy, and nothing to cause lost sleep. Happy New Year!
Is the quickest way to find leaks not a smoke/fog test, saw Ed China doing it on Wheelers Dealers, when I used to watch it.
Hello there If you Look behind the glove box and the wind screen wipers where water Channel is runs away because they do get bogd Up
Easy way to clean drain holes is to use the spring wire that is used to hold net curtains up, just cut one end off and push it down the drain holes. Did a perfect job on Mercedes and stopped the water problem, then clean up the seals and apply some GummyPledge onto them.
Jack, go get a can of grey paint, and a roller. Nothing could make the BisMerc look any worse!
You can get windscreen leak sealant that runs along the seal and finds the leaks. I've had some success and some failure with it. Might be worth a go.
Who would have thought a water leak could be so interesting? :D Great vid - thanks!
Just a thought Renaults and Vauxhalls have a problem round the wiper motors under the trim panel there is drain holes ether side that take the water down through the front wheel arches, they block up and the sunroof drain pipes also block up doing the same thing, used to just blow them through with an airline to clear them…
