I replaced the resistor to front heat and air, now the rear is just blowing cold air, do I need to have it re calibrated? It isn't showing a code either, could the rear have gone back to its default setting or something else possibly bad also?

Was it the blower motor resister that was replaced? If so, that only operates fan speed. Let me know.

That shouldn't have affected rear temp.

Kinda coincidental that rear heat quit working all of the sudden after replacing front resistor! So what could it possibly be?

Is the fan blowing cold air? Have you checked the heater core for the rear? Is it getting hot>?
