There are quite a few players involved in getting the heat to the cabin, and trying to replace all of the possible suspects gets expensive fast. It could be something as simple as a faulty blend door/actuator, or a number of other things, but it's all guesswork without diagnosis and testing..... Could the problem come from the heater core or thermostat. ...
Thanks for infoThere are quite a few players involved in getting the heat to the cabin, and trying to replace all of the possible suspects gets expensive fast.

I'd start the process by finding out what the actual coolant temps are, but others might try some other testing instead, and another group would just fire the parts cannon. This is your vehicle, so how to proceed is up to you.
Thanks for the info, I’ll try that.Suspect you have a leak in the coolant system that is letting air in. Do you hear sloshing in/around the glove box area?
first thing to do is to burp/bleed the coolant system (easy to do, check youtube). If this being the heat back to norm op temp, then there a leak somewhere. Next run a bottle of coolant dye to find out where the leak is. Given the cars age (in years), it is boarding where a lot of rubber/seals are getting old
