A good place to find such information is at WWW.AutoZone.com.
You can select your make and model of vehicle, go to the "how to" section and in many cases it will give you the instructions for replacing various parts and it is free.
AllData.com is another resource that you will pay less than $30 a year for your first vehicle, it is an on-line service manual web site, very good.
Below is the procedure for replacing your heater from the Auto Zone site.
Good luck, let me know.
