Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) Air Conditioner problem

I have a 2025 Plus Four and have a question re A/C that I hope you can help.
When the A/C is on and the temperature is turned down, the cold air that comes out is replaced by warmer air( not as cold) then after a minute or two the cold air is back and the cycle repeats. Is this normal or do I have a problem.
Thanks for any help.
