The lock and windows of my 2001 Oldsmobile Aurora dont work I want to know if the fuses or the relays dont work.

Easiest way to do that is grab your owners manual. There are two fuse boxes in that car. One under the hood on the left side, same area as your battery charge terminal, and the other is under the back seat, with the battery. There are fuse charts in the owners manual. Just look for fuses and relays that relate to the doors, locks, and windows. Pull them and check. If you arent sure, just replace it with a new one, fuses are inexpensive!!! Take care :-)
