my heater has been messing up for a long time I don't know how to fix it when it works it's either all the way cold or all the way hot I can't adjust in between it mostly doesn't work when I try to go from cold to hot it'll go from hot to cold with no problem when it works there's a pop in the heater Box And the door will open And I have heat but it's full blast I can't ever control how much heat it tells me the door is hanging up in the heater box I know I can manually open it in the engine bay but the arm is really hard to get to in my 2004 Honda Civic LX is there a way I can get in the here box to try to repair the door. your help would be much appreciated because I have a leak in one of the corners of my windshield and during the winter it fogs up almost instantly when I turn the car on so I really need to have control over my defrost and the heat thanks in advance I appreciate it i'm really short on money otherwise I would put it in a shop
