Recently I have noticed a small puddle of water on my rubber mat on drivers side.
This has been either after a heavy rain fall or when being washed.
It seems to be dripping from near the hood / fuel buttons on the dash.
My vehicle is a 2006 Toyota Landcruiser Wagon and a roof rack was fitted approx five months ago.
Was curious if any other cruiser owners have experienced this problem.
Thanks in advance on any feedback

Hullo Munji
If you have a snorkel, it might pay to check the screws on the brackets for tightness and maybe use a tad of sealant if necessary.
A couple of years ago I had the windscreen replaced and the fitter obviously undid the screws in order to move the snorkel tube and then did not tighten them again.
Having tried to find the leak for ages and failed, I finally(!!) had a gander at Lcool - and there was the solution.

Remove your roof rack Buy a tube of WINDSCREEN SEALANT. Poke some in each thread hole and then coat the bolts with it . Make sure the rubbers under the mounts arent perished.

Bolt it all down and no more trouble From one who has actually done it.


Windscreen sealant never sets hard and takes movement. Silicone sets more or less solid and will eventually pull off one surface or the other.

I used to be a roofer and have had experience of fixing others mistakes of using silicone rather than a flexible sealant like above or Sikaflex or Secomastic.

as mentioned above, it's likely not sealed properly around the bolts that hold the roofrack in place...a common complaint i've read numerous times.

Common problem on the toyota wagon is water leaking in through the top of the windscreen on the inside have you had a replacement windscreen recently? If it is the problem you should be able to see where the water has run down the inside of the windscreen, if you can't find it tape some newspaper up on the inside of the windscreen next time it rains will show up if the problem. If so get it resealed only way to stop it.

Do you have any additional wiring coming through the big grommet on the drivers side? If so, water can sometimes track along the wires and straight into the cab. Its best that wiring is directed upwards from the engine bay side when going into these grommets.

I'm not saying this is where the problem is, or it could be a coincidence , stick a length of fence wire up the A/c drain tube , Hornets build a nest in the pipe, next thing you know you have a dam of water under the dash .

Had a problem with that but it is on the passengers side.

Was resolved by taking end panel of the box and siliconing around it.

Fluid was running back into the cabin instead of out the front end of it

Munji, see my thread from 20 Nov. Thread ID 110197. I too have a 100 series cruiser. 90% sure it will be the roof rack leaking. Have a look at your racks and see if there is something rubber under the metal foot of the rack. If not water will seep in via the bolt threads.

You will also need to check under the flooring. Mine has vinyl floor with carpet underlay. The underlay was saturated with water which will cause rust in the floor pan, maybe electrical issues with the wiring under the floor and also give you condensation issues on the inside of the windows.

The easiest way to check the flooring is pop the covers up that are on the sills and then you can lift the flooring a bit. You'll need to check all 3 'sections' of the car, boot area, passenger seat area and front cabin area. Mine was worst in the boot and front cabin area.

What sort of roof rack did you get? Brand name one?

Have a read of my thread anyway.

Mine is a Tracklander full length.
I will check bolts on roof rack as it has only started since it was mounted.

Pull bolts one at a time Squirt windscreen sealant in each Thread hole Put them back. Problem solved Guaranteed.
