the battery goes flat over night and the heater panel buzzes, someone said it could be the heater resistor, where is the resistor located

The 03 has a battery with a built in capacitor which will not hold charge if your battery needs replacing. Your car is draining overnight due to all the systems that remain active even when the ignition is off, such as alarm, immobiliser, the little light on the gear selector and window lock button. A new battery will fix the problem instantly.
