My 2001 ls430ul driver window occasionally goes down very slow when opening.

The window rubber which presses against the bottom of the window along the top of the door

inside starts to turn down with the window and slows or stops it, usually in the morning.

At times when the rubber does not go down, the window works fine.

Going up is never a problem.

Can the window be waxed or can silicone lube or something else be used to stop this?

Thanks for any insight or suggestions.

You could try a little Shin-Etsu grease, you can find it at a Honda dealership, it's basically made for weatherstripping.

What you want is a grease without petroleum. You could also use a silicone plumbing grease but the Shin Etsu works better.

But there could be something else going on that has nothing to with the weatherstripping.

 

I have the same problem and am looking for an answer too. Any help will be appreciated. Mine is a 2004 LS430.

 

Each LS430 door window has a rubber seal that goes all the way around the opening, against the glass, to seal out wind noise. The rubber seal is part of the "window glass run" that is attached to the door with 5 rivets.

Can you remove the inner door panel and take some pictures on how and where the rubber seal turns down? There should not be a gap large enough for the rubber to turn down. Suggest you take a look at the other door and compare the width of the gaps. The window glass run may have been damaged and you may be able to bend it back in shape.

Worst case if you have to replace the window glass run, SewellParts.com lists them for around $150 USD.

 

Tks. for the advice. I bought a 9 oz.bottle of 3M Silicone lubricant (wet type) for cars and sprayed it on the plastic seal of the window frame. The window works up and down smoothly again like a miracle. I sprayed all 4 windows as a preventive measure and more than half of a bottle is still left. Tks. again.

 

Just to update my window sticking problem.

I did as Coulter suggested with the Shin Etsu silicone and now the window moves up and down flawlessly.

Thanks for the comments and suggestions.

My 02 LS430 has this same problem. I'll have to try that Shin-etsu grease on it.

 

Déjà vu...

 

I had exact same problem on my 01 ul. Bought shin etsu grease and put it on all 4 window wipers. From experience use very little, so that you don't have foggy, grease stained windows every time you roll them up
