Mitsubishi Spac Star 1.0 year 2016 – problem with heating

Hello community, I’m new and this is my first post. I’m honest and I have registered especially for a problem that I have with the Space Star. Because I’m not a car expert, I don’t want to be active in your community. I hope you accept this and still want to help me. Now to my problem: Something’s wrong with the heater with my Space Star 10 year 2016. The two right-sided ventilation openings blow clearly cooler air here. from as the two left side. Almost left warm, right cold, with maximum heat adjustment. What can this be? And does the five-year guarantee cover this case? I thank you in advance for your support! Greeting, leinad
