I just completed a heater core replacement in my 2000 Grand Cherokee. Now my heater blows hot air when my temperature control is set to low and the cold air blows when my temperature control is set to high. What could cause this and how can I fix it?

I want to understand learly first, when the TEMP is set to low, hot air blows? So it is basically doing the opposite of what you are requesting? Is it possible that 2 of the vacuum lines are mixed up at the blend door control?
