AC temperature change is slow going from hot to cold

I have a 2001 SLK230 and the AC switches from hot to cold slowly. When it is on cold, it is very cold and as I move it to hot, the temperature gets hot. The problem is when I switch it back to cold it will take a few minutes to get back to the cold temperature. I have cleaned the douvalve and I do t hear any clicking or thumping noises when changing the temperature. It is duo climate control and it is occurring on both sides.

Check the blower box actuator under the instrument panel. It controls the temperature from hot to cold. It may be defective.
