I bought the car over the summer and the AC works pretty good but the heat doesn't work at all. I did a radiator flush and also a heater core flush. Every thing looks to be fine. I also checked the heater core valve and it works fine when I change the temperature. It moves from left to right and right to left. There is no air in the system and I have been using Honda blue antifreeze. The car warms up fine no issues. It does not overheat. It stays about 3 marks away from the middle of the hot and cold gauge. When I have the heat on all the way to high, the driver side is ice cold but the passenger side is warm. Any help would be greatly appreciated. If it makes any difference, the car doesn't have navigation and its dual climate. The 2 hoses going to the valve are hot
