My divers windows has developed as scratching grinding noise as it goes up and down. It’s sounds terrible.

It could be dried salt/grit from roadspray.Wash and rinse your windows a few times and hope you haven't scratched the glass.

@DavidCM
Window   scratched 😭 

how do you suggest to wash ?

 

I was going to buy silicone spray 

[DavidCM]

Try soap(car shampoo) and water a few times,then lower the windows and repeat.

[DavidCM]

Oh....and do NOT use silicone spray..

Don’t put silicone on glass, it will smear and is almost if not  impossible to remove!
I have some Autoglym products for glass cleaning as shown below which are very effective along with their “Glass Polish”

Another cause is crud build up in the exterior lower glass seal, I gently pull it back and use an old toothbrush with car wash solution to clean it out before rinsing thoroughly.

Just realised Autoglym products have a Royal Warrant, I can just imagine the King popping out to clean his car.

If it’s good enough for his Majesty it’s good enough for my Lexus 😀

I wonder where Andrew warms his hands if he washes his car in this weather?

you can use the silicone but only on the rubber seals to help the glass glide smoothly

it will also help to stop the glass from freezing to the seal during the cold spells we are all having now.

So I don’t  need to strip the door out or take off the door card and get to the motor ?

Remote and accurate diagnosis is impossible but try the above suggestions first then we can go from there if required 😀.

Silicone attracts dirt and grit, best avoided totally. 

Use something like Gummi Pflege on the rubber seals to condition and prevent freezing

Yes I’ve got this as use on all the rubbers on the roof on  my 250c

So I’ve cleaned and washed but still the same horrible noise

Joking all aside - drive over a very rough road to try and dislodge whatever might be there.

Failing that it looks like a door card removal.

 

Others may have better suggestions.

 

[Johnlex]

what advice do others have ?

remove door card and plastic and get the motor behind and check everything?? What lubricants 

[steve2006]

Perhaps you could post up a video to give us a better idea of the noise?
Renault Meganes we’re notorious for seized up cable operated window mechanisms due to water and crap ingress but Lexus use the more reliable conventional scissor type arrangement and decent grease.
