i recently got an '00 civic si and i noticed that the passenger window moves really slow and only goes down about 3/4 of the way. i havent taken the door panel off to check it out yet but does anyone have any suggestions on what the problem may be? oh by the way if anyone owns a civic thats lowered an inch and a half with '16's and 205/40 tires, would u mind sending some pictures?

 

try some silicone lubricant and spray some along the window track that should help the glass slide easier. as for why it only goes does 3/4 of the way i have no idea. might want to check out the arms
