The 1995 Ford Windstar doesn't have a dedicated Daytime Running Light (DRL) module in the same way later vehicles do. The DRL function was likely integrated into the body control module (BCM) or possibly even the instrument cluster. There isn't a separate, easily identifiable "DRL module" to locate.
To diagnose DRL issues on a 1995 Windstar, you'd need to consult a wiring diagram and use a multimeter to test the circuits involved. A professional mechanic with access to diagnostic tools would be best equipped to handle this.
