Ac blowing in one vent
Why is only one of my vents blowing cold air the others are blowing relatively warm compared to that one I just replaced the blower motor and the cabin air filter

Probably a stuck or broken blend door actuator. Try moving temps way low and way high several times to see if it loosens it.

Do you have a diagnostic tool to read the codes? I forgot, also try moving the air around from the various vents too. I know you probably already did that but just want to be sure.

If the coil provides cold air for one vent it means it provides it also for all vents that the system settings ask for. It is NOT about low refrigerant in the A/C system, It is about the air flow mixer valves that control air temperature coming out of the vents.

There is only one evaporator coil for the A/C to cool the car unless you have the dual system that I think has another one for the rear passengers.
