My a/c is stupid. About 2 weeks ago i was sitting at a light and it stopped blowing completely. No air what so ever. Not hot not cold nada. when i get up to about 40 mph it will start to blow cold air. yes the air is cold at 40 under 40 no air at all and i dont know what is causing the problem. I checked the air filter, I checked fuses, the fans come on, i do not have a cabin filter at all. We charged it and still nothing. I tried the pressure wash and got nothing too. If anyone has any suggestions im open. I live out in the sticks in central Texas it hasnt rained in months and its averaging 112 degrees here everyday. Im dieing, and the nearest dealership is 2 hours away.
