A good auto sparky should be able to replace it. As long as you can source the relay to solder in. Holden dealer would replace the BCM only - or send it out to get repaired. What part number & level is the BCM. low, mid, lux?

Unless the relay contacts have welded themselves, its unlikely to just be the relay, more likely the device that drives the relay, so you may need to try and obtain the schematic diagram.

It is just the relay that needs to be replaced. I wrote a guide on replacing them and posted it to just commodores. Have a read. Shouldn't cost too much to fix.
Don't replace the whole bcm (at huge cost) when it's just the relay that needs replacing.
Also - don't leave it until the heat opens the weld in the light and you then have to glue that up.
