Heya guys, been getting used to doing my own fixes for my car, so I’m lacking a bit of the maybe common-sense knowledge for some of this stuff.

What does the housing actually do, and should I replace it to be safe?

For posterity, I have a 2010 Avenger SXT 2.4L

    Thermostat stuck open makes the car run cold, thermostat stuck shut overheats. Off the top of my head, your heater core could be clogged, you could be low on coolant, or some HVAC system issue that I know little about.
