Default question on AC controls

I replaced my AC controls with a unit from a 99 into my 04. After swapping out the unit, I now have heat blowing from center and drivers side, and cold air from the passenger side. This when it is in AC mode.
When I move everything to heat, both sides heat. Anyone know what could cause this? Seemed to be a plug and play and was working fine with old unit. Only replaced due to no lights, display. Are the units not compatible?

I guess both controls were dual climate control?
You know there is a simple fix for the lights?

The Dual control units can be swapped between all years.
