aveo lt bj 08 too weak heating?

moinsn, had to dodge again on the aveo from the vadder recently. there fell on me on the car heats hardly. motor is warm after a short time and comes as it should on temperature. heating naturally set to 23° – nothing only icy cold on 27-28° the wummering goes off in the inside room – lukewarm air which indicates itself as heat on attack 31-32° very loud wammers and noises from the fan, after the motto I get the last out. – what seems to be heat it is by no means. i ke nn that of my opels, from 23-24° we slowly come to sweat. I directed vaddern to the friendly, that a nearly 2,5j. old car with 17tkm on the clock should not have such a pathetic heating. vaddern came back, the master of the friendly has comforted him is now like that. find yourself with it!!! the car was bought at a large opel chain nail new, which are not exactly the fittest. it would go in the frame of the rest of the new car warranty, the car to my f to bring oh (a small family business) and then to have it billed with the original. if the heating problem is unnatural? thank you and mfg
