Good morning,
This requires a full dash removal to access the heater housing to remove it just to get to the heater core itself.

It is an involved job and there are no real short cuts for making the job easier.
I attached some YouTube videos for you. The first 2 are part one and part 2. The last one is a complete.
Make sure the thermostat is working as well. If it is stuck open, it will give low heat.
