The A/C and heating in my car has seemingly stopped working almost completely. No air blows out of the vents. I ran the diagnostic codes and got a "no codes" message under the ACM. I haven't taken anything apart yet to look at individual components because the area is difficult to get to and I'm not sure what I'm working with yet. I have checked all of the fuses, and didn't find any that were blown out or needed replacing. If you put your hand directly against the vents, you can feel the tiniest hint of very cold air, but it doesn't blow out at all. You can feel the coldness radiating from the A/C parts inside the engine if you touch them. There is no noise at all from the fan that I can detect, but I think I hear changes in the sound of the engine when I am messing with the buttons on the A/C. I'm very much hoping there is an inexpensive solution to this problem. We live in the Utah desert so it's really hot here a good part of the year and our budget is super tight. Any advice or suggestions would be be greatly appreciated. Thanks! :)
SOURCE: air and heat not blowing air through vents
Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.
