This the most ridiculous thing I've ever heard of. The whirring noise is the blower motor for the heater. You can fix it by removing the glovebox and replacing the blower motor. It went out when I had it and I put in an after market blower and it hummed. It was pointed out in one of the 12 videos describing the vehicle I posted before selling it. Please save yourself some money and stop letting your Isuzu dealer butt-rape you for all you're worth. Total nonsense. It takes less than half an hour to pull that part and put in a new one. All you need is maybe a small wrench and a screw driver.

Or you can pay someone thousands more dollars to fix things that aren't broken. I spent more time under the hood of that VX than anyone else every will. And laying in the dirt underneath it tinkering and fixing things and learning about it and exploring and understanding it. I wouldn't be surprised to get on here one day and see complaints about the dealership saying the VX's blinker fluid reservoir has run dry and caused a rod to start knocking in the rear differential. Buy a tool set and stop letting them ride you.
