Have a 99 Civic Si. The driver and passenger windows go SLOW up and down wehn its cooler outside (work fine when warm) Last night my driver side window decides to, not want to stop going up. Basically like banging the top of the door frame. Any ideas. Im in TX. and its hurrincane central lately please help before Im screwed.

 

I'd either say your motors are going out or you need to lube the tracks/slides/guides (whatever you want to call them).

And can you give any more detail as to the 2nd problem? I had a problem with my old window to where every time I tried to close it, it would start to make a loud banging noise and would sort of hop. It would always come within a 1/4 of a inch from closing all the way. It turned out to be a damaged tooth on my regulator. The teeth on the motor would try and find the next tooth on the regulator but the window would slide back down when it missed that broken tooth and would just go through the same process.

 

prolly gonna need a new window regulator w/ motor

 

I've noticed on my '92 that the front windows always go up fine regardless of the conditions but if it's cool outside (prob. anything below 60) or if it's just rained/high humidity that it goes down slow and you can tell the motor is straining. Because of this I avoid using my front windows (rears are fine).

I'm assuming it's something to do w/ the tracks but I've looked and can't see any problems, so maybe it's electrical.

I know on some Accords ('94-'97 I believe) that what appears to be a window motor going bad can actually be the window switch itself, bad contacts, whatever.

I'm not sure if that actually helps or not h:

 

spray some silicone or other lubricant in the tracks.
