its most likely down to friction!
halfords sell a window lubricant you squirt down the channels.
if not some wd40 should also do the trick.
but if you can hear a sort of crunchy noise coming from behind the pannel its most likely the mechanism thats on its way out.
honda window mechanisms work with a tensioned cable running through a series of pullies and passing through the motor. this cable is simaler to that you find on the brakes of push bikes. what i mean is that its made from loads of smallmetal cables wound together to form a bigger cable. so if one fibre snaps its gonna unravel and start to restrict the movement through the motor and pullies.
window mechanisms are really easy to replace if your good with your hands only a few 10mm bolts connect it to the window and door. not sure though if youcan use the mechanismout of a ordinary civic depends if the doors are the same size?
Ive had this issue on my old civic, and its slightly here with the Jordan, bit of a Noob question, but what classes as 'silicon' spray? Ive always put WD under that title. Where can you purchase said spray?
Ben
so you never fixed them, you ended up replacing them. honda aint the cheapest to pay either
Well i kinda fixed it... with new parts lol
i tryed everything else thats been posted up and got so p#!ssed off i got the bits to fix it..
theres also a 10mm bolt that holds the regulator in.... closest to the rear of the car that has a small amount of adjustment that tips the glass front and back... if you get it right (after a few test runs) it helps the window run smother ...
i found that using WD40 wasnt very successful as it would end up about 3 -4 days later with the window going very slow again!! Also then dipping down the side skirts and when it got dirty left a horrible greasy mess!! I then found some silicone gun oil (i guess any silicone based spray oil will do) and this done the trick perfect and for the last week no build up on sideskirts at all and also windows still going up and down alot faster and smoother!! Hope this helps some people
MAN I TRIED USING WD40 but nothing so what i did just gave up lol
