Yup, those hose ends are to the heater core.

I'd probably pressure test it and verify if its busted. It's a dash drop job to get the heater fixed.

A common mod to help control pressure to the core is to put a 13mm socket into the feed hose (left hand hose when facing it) as apparently these heater cores can balloon under repeated hard acceleration.

Well looks like this'll be another learning experience then, I've never done heater work but I've had to repair a few a/cs. I did watch a video on how to replace the heater core in a same year Towncar, it definitely looks rather involved but should be manageable. That 13mm mod is pretty ingenious.

I found a 12v portable heater under the passenger seat, neat little thing, I've never seen one before, I tested it and it still works. It may come in handy if it gets cold before I get the heater situated:
