Updates as promised. Early this morning, I was having another look around and found the water coming off the blower motor. So, first step was to remove that. I took it out from the passenger footwell area. Just unplug one cable, and then 3 screws. There was not a lot of water in there, but it was definitely wet. With that off, I threw a large mixing bowl of water over the windscreen and it all ran off into the passenger archway (thanks @IS300FSPORT). I left it a while and no water was appearing in the passenger footwell with the motor off, even with this huge amount of water. Tissue in situ to try and catch where it was appearing from. So, it seems more likely to be water from the air conditioning system. Perhaps water was just slowly dripping out of the motor, hence the leak. I hope I have reseated the blower motor properly. It seems there is a black spongey seal around the edge and in one place that was glued down, but for most of it, it was loose. Maybe a new gasket can be purchased, if needed. I am keeping an eye on this. There is a short rubber hose attached to the blower motor mounting frame, and connecting to some plastic that runs behind the centre console. I assume this is the pipe that runs to the underside of the car, to let out any AC condensate. See photo below, can anyone concur? I pulled one side off and it was mostly dry, certainly not full of liquid at all. But as noted, my car is parked at an angle, sidewards, with the passenger side the lower point, so whatever water was in there may very well have drained into the blower motor and therefore the leak. If this is the condensate pipe (seems like it, this page has part 88539C or 88839 30010 at the top, and a Google shows me it is called the "cooler unit drain"), my efforts should be focused on how I can get this cleared. Perhaps poking and running through a long rigid something into this pipe will clear it, but who knows how long the pipe is. Any thoughts or advice appreciated. Maybe this is the best and easiest way for us DIYers to clear this out, as the pipe under the car is very difficult to get to, even if you have a ramp. Lots of garages with a backlog of work, so I am troubleshooting all I can till I can get someone to look at it.

Thank you Colin. The water seems to be dropping from further up toward the firewall, so it’s not looking like a seal. Will check the scuttle panel for water blockage. Once it collects there, do you know where the water drains?

Thanks! Where is this drain tube under the passenger arch, do you know?

Still more water leaking today. But I’ve not driven today and so the air con has not been running. It’s also rained a lot today. So I’m thinking it’s more rain and not so much the condensate pipe. Does anybody know where rain water drains and how it might be getting to the passenger footwell?

No sunroof on mine. I had read about drainage being blocked on those with sunroofs, but I assume mine will have no such drainage. Is there a diagram for where all drainage holes / runs are? I’d happily check all those. No immediate blockage under the windscreen, I keep on top of it but I’ve no idea where that water runs to. I failed to say, I park my car on a slope. But I park it sideways (so passenger side is lower than driver side) so as not to put pressure on the hand brake. But in my years of doing this, it’s always been bone dry inside. Again, the windy rain and this position may simply have been a bad combo. But we’ve had similar or slightly worst before, but no water inside. I suppose it’s hard to rule this out unless one firstly knows where water can enter and drain from the car.

Thanks for the comments, especially on new year’s day. I have had the car somewhat disassembled this morning but there’s not much I can see. The passenger footwell under tray (which the footwell light is mounted to) had quite a bit of water on it when removed. It’s not been possible to see where it is coming from. Cabin filter entirely dry. No windscreen change recently, I did look at a previous comment of yours @wharfhouseand saw you mentioned this, but not so. Thanks anyway. I recently had my condenser cleaned (bad smell) and the condensate pipe was presumably therefore flushed so it surprised me that this wet carpet appeared. However, since that cleaning, I’ve kept the AC on all the time. Perhaps it’s just the sheer amount of windy rain we’ve had all over the country (I am in the Midlands and it hasn’t been anywhere near as bad as further north). But windy it was, still. Has that just caused water to get in somewhere unusual? Off to a specialist sometime soon to look and resolve. Will keep an eye on it in the meantime. Will keep you all posted.

Hi All Happy new year! My Is300h has some water in the passenger footwell. It sounds like the air conditioning condensate pipe is blocked and backed up, but I understand there are some drains that might be blocked too. Anyone got any ideas and diagrams to help me work out the matter please? I am worried it will begin to cause issues with the electronics!

Find a used approved and you’ll get 12 months of warranty from the day you buy. They are solid and reliable cars. That will be peace of mind for you, if you’re afraid to pull the trigger. Are you inclined to continue with dealership servicing? You get warranty for up to 10 years if you keep up with dealership servicing. That will give great peace of mind too, as if something goes wrong (you’re in the premium sector now) then it can be costly. Thankfully issues are rare. I personally operate without relying on Lexus warranty. Specialist servicing instead of main dealer. The app is quite useless. Pretend it is not an option. There is no auto heated windscreens or connectivity. You might be better spending money on an aftermarket upgrade of the screen, adding in Apple CarPlay or Android Auto functionality. ML audio is nice but if you don’t appreciate the audio, no need for the upgrade. All editions have Bluetooth audio and calls. Not sure AA inspection is worth the paper it is written on. Find a fine specimen with a careful previous owner / enthusiast. I personally prefer the F-Sport styling.

I don’t think it’s an issue. My CTEK one has LEDs that are constantly flashing and I’ve never had a flat battery. The power draw is very minimal.

For those with a CTEK charger like me, I was contemplating one of these for a flush OEM look: https://www.ctek.com/uk/battery-chargers-12v-24v/accessories/car-accessories/indicator-panel-1-5m For now I have the dangly thing in the boot like pictures above, that functions just as well, so I’ve held off. also afraid to disconnect the battery for fitting something like this after all the issues people have had with fried head units!

I had this issue earlier in the year and ended up replacing the sensor myself. If it’s the front two in the grille it’s not too hard. A good OBD dongle connected to your phone via Bluetooth with a free app will help you pinpoint which sensor it is. There’s a different error code for each sensor Swapping a known working one on your car (all sensors are the same on the car), clearing OBD errors with the app, then seeing if it flags again will pinpoint if it’s a wiring issue or just a duff sensor.

What is that white funnel-like piece that OP was turning in the video used for?

Please do go ahead and share here!

Sorry to hear of the great expense. This is what insurance is for however. Can you not claim?

Definitely need to do this in mine. My biggest frustration is the low pointing lights.

Looks fantastic! From the driver seat, do you lose view of the right edge side of the screen? Anyone faced any durability issues of their aftermarket screens? Car screens get some pretty strong heat and direct sun, even in the UK at times, baking in the sun. I am somewhat tempted to undertake this but I’d hate to be undoing this work in 12-24 months if the screen dies, putting the factory unit back in.

But would you just do it and use them anyway? Unlikely it’ll cause any issues for you.

If I purchased my Lexus today, on the premise I’d get 15 years of warranty if I kept on having the hybrid battery check each year, I’d be somewhat miffed if the goalposts moved. It’s a good job I don’t care to get it checked and therefore an not relying on the warranty Yes, terms may change for new customers, but if that’s what the salesperson and their literature said when I went for it, it ought to be honoured.

Good spot! Save a copy!

I imagine that, if reasonably competent and not afraid you will break a clip, that you’d do a more careful job, and therefore an arguably better job, than most tradesmen. After all, it’s not them that will have to live with a rattle. They’d also likely dispute they caused any rattle as well, even if you accused them so.

Took mine off after my son spilled some water. Wanted to dry it. Just needs a good tug to get it off. No bolts to undo. 2013 Is300h F-Sport in case it’s changed on facelifts.

Nice gesture! Are you sure you don’t want anything for it? I’d put it to use, I have the joystick and my car has an SD card, albeit an old version now!

Price now up to £270!

Looks great. How long did it take to install? And where do you situate the unit they provide?

I understand it can be dangerous due to voltage. So be careful. I had read the best way is to disconnect a fuse for the headlamps in the under bonnet fuse box. Someone with more experience may be able to affirm this.
