2011 BobCat CT-450 Cab Heat Issues

[RobfromManitoba]

Howdy all, I have a 2011 BobCat CT-450 (Engine stamp actually 2009) that I bought used - cab model. No fan action from HVAC control despite there being power to the control. Main 25 Amp HVAC fuse is fine. My coolant system is fine, at least tractor is not overheating but comes to operating temperature. I'd like to find the fan and heater core to check things out. It's really cold up here in Canada to use even a cabbed tractor without heat for snow clearing. Can't get either the local BobCat or Kioti dealers to give me any hints how to access that stuff (tractor is really a Kioti DK45HSEC that BobCat put their own paint and loader on between 2008 and 2013). Any insights for trouble shooting? I'm guessing I start removing screws in the panel at the top, rear of the cab, but before I commit any really stupid errors, thought I'd post and see if anybody else has done this. Thanks all. Rob
