2003 Chevy Cavalier Relay Assembly/Express Down Module

Electrical problem
2003 Chevy Cavalier 4 cyl Automatic

I need to find out where the Relay Assembly/Express Down Module. I cannot find where it is. I have looked in the fuse boxes, the center console and under the dashboard. A speed reply would be wonder we are expecting rain and the window is down. To bring it up I need to replace the module soon (today).
