I think the Bitron unit is hidden under some bracketry behind the nearside headlight, but don't quote me on this.
Fan problems on the Xantia are frequently due to bad contact/wiring on the three relays between the fans. They should both run at half-speed with the air con on and full speed when the engine temp gets too high.
Try pulling the brown plug off the sensor on the thermostat housing, the fans should run at full blast.
