Hey guys probably a silly question, getting some really frosty mornings here and my ute is taking atleast 10 minutes to semi defrost the window so I can see out of it. When compared to other events not even half the amount of air is coming out. Is it a blocked filter somewhere or something? If it was a leak I'd assume all the heaters would be weak.
Also the first heater setting doesn't work, cant even force it to click onto that setting, is something stuck?

Any help appreciated!
