Clr

I was in the same situation when I bought my Jeep. Very little heat. I detached both heater hoses. Loaded the heater core with CLR. Let it sit for a while. And then flushed it out REALLY good. That was about two years ago. The heat has been excellent ever since.

Of course you should NOT do this because CLR is corrosive and will eat the heat core....

So I guess you'll just have to replace the heater core... :)
