1997 Chrysler Cirrus heater not producing enough heat

Check the thermostat and heater core.

I asked this question in my last message, the fact that the car was not producing enough heat was just the subject. Thank you

I have changed the thermostat and am now looking to replace the heater core, my question is, how do you replace the heater core on this 1997 Chrysler Cirrus?

I was double checking if it was the thermostat or clogged heater core that's causing it not to produce heat. Replacing the heater core either its leaking or it clogged-up-nothing was mentioned on it-Sorry Heater core removal
