It is expensive, and it is not an easy job. I used to work with some really good Volvo guys and they did not like that job. As to the bypass issue, just follow the hoses that carry the hot coolant to the heater core and join them together in the engine bay, viola, bypass surgery. There will be no defrost and that could be unsafe my friend, beware.
