Weak blower normal at the Clio?

Hello together, would be great if you could help me with a short question. Is it normal that the blower is so weak at Clio 2? On level 4 you can hear the radial fan running under the windshield and also clear air noises but from the nozzles comes only a lukewarm ventilation! The blower stages all work, the vehicle has climate. Is this normal? At the front of the windshield I have already dismantled the covering and felt with the hand if something i n the intake opening is in place, but the radial fan is not added. Greetings
