With car at operating temp. Feel the hoses going to the heater core. (back of engine comp against firewall). Are both hot? Is neither hot? Is only one hot? Post back what you find and I can explain what it means.

If you haven't figured it out yet, there is air in your heater core. Pressurize your reservoir with an air compressor
