Welcome to the forum, thanks for the donation. I have been looking for an exploded view of hvac system, haven't found it yet. Under the hood, at the firewall, where the heater hoses plug in, is there a panel with screws, if so, remove the panel, see if you can get at the heater core. As far as removing the hoses form the heater core, I don't fool with it, I use a utility knife, be careful, split the hose on the core fitting and peel it off. If that makes the hose too short, get some new hose.
