So yesterday I was driving home, it was really humid and my windshield started fogging up, I set the vents to blow on the windshield, and set it to the hottest setting, and it cleared up the fog. I set the vents back to blowing on me, and turned the temperature back down to cold....except it kept blowing hot air. Same thing this morning. Whether the AC is on or not, no matter which vents the air is blowing through, no matter what the temperature setting is, no matter if recirculate is on or not, the air coming out blows hot. Any ideas? UPDATE: So it was POURING out when I got out of work; I was feeling around under the dash on the drivers side for where the screws are I would have to remove later in the evening. I knocked on the panel to see if I could hear where the unit was. After that the cold air started blowing again. Guess my magic hands fixed another problem. Thanks everyone!
