The clock and radio display in my 2004 Holden Statesman won't turn off

The clock/radio display in my 2004 Holden Statesman will not turn off and is draining the battery. I have tried pulling fuses and relays but it won't turn off even when the car is completely turned off and all doors are shut.

I'm not sure how an electric piece of equipment continues to function when its fuse or relay has ben removed, so maybe you need to check that you're pulling the correct fuse. The car's owner's manual should contain a list of fuses, their location and what circuit they relate to.

In any case, problems like this one are often the fault of the car's body computer which can fail, allowing all sorts of random errors to crop up in anything from the climate-control stuff to the central locking. If that's the case, a new body computer may be required, but these can be obtained second-hand to keep costs down.

But before you do any of that, try these simple tricks: Using the key fob, press the door lock button and hold it down for at least a minute. Sometimes, this is enough to reboot the computer and restore normal settings. The second thing to try is to park the car and disconnect the negative battery terminal. Wait at least an hour (overnight is better) and then reconnect the battery and see if the car's computer has reset itself. It doesn't always work, but it's free and definitely worth a shot. Just make sure you have access to the radio's security code to restart it after disconnecting the battery.
