Flush your heater core. I was having the same problem until I flushed it and I was amazed as how much stuff was hiding in it. After though my heat works like a champ

So, u did the flush, burped it, checked the blend door and made sure u have at least a 180F t-stat? When u did the flush, was a good strong stream of water squirting out a heater hose? 'bout the only thing left is a possible weak water pump
