Hi I own a 1998 buick century custom and I am having problems with my windows. The front passenger window will not go up or down with the door switch but the drivers swith will open and close it. The back drivers side window will not go up or down with either switch. and the back passenger window will only open with the drivers door switch. What is going on with the windows? Any ideas on how to fix this problem?

 

Welcome to the forum! Your passenger side front and rear windows could be a fuse, or maybe coincidentally both window switches went out at the same time. Your rear drivers side sounds like the regulator has stopped working. I had the same problem with my rear passenger side when I got my car in january.
