The reason the windows are slow is because the rubber weatherstripping that the window rides up in is dried out. Its easy to tell because a new "rubber" will be black and the old one will be a dark grey and really dry. If not changed it could cause the power window motors to burn out. Its expensive but worth it, its like 74 after tax from Honda. My rear windows are fine, but I had to replace the front two. Its easy to replace the stripping too, its just a bit hard to align it up for proper placement.
I hope this helps

 

I replaced that ****. no improvement. its just a shitty design to start with. honda has admitted it.

 

yea, my car was garaged for a few years. my passenger side window moves VERY slow. I sprayed some silicone lubricant on the side and it did improve a little bit.

 

push it

 

Armoral is the cheapest fix, my windows work like new

 

any chance a more powerful window motor would help? any easily swapable power window motors?

 

its always the passenger window mine is AFU to..

 

This is like having the smallpox vaccine and not using it.

 

Funny i have that problem too, but no need to go to honda and get overcharged. Im curious about these sprays and if they are really effective. My two front windows are also SLOWER than the back two. I mean which one out of all the sprays that you all have mentioned the best for this situation?

 

I give up.

 

I've used the silicone spray with good results. It's good for the rubber too.
