Okay, my A/C just out of no where just started blowing hot air instead of cold. all the vents work it switches to defrost and everything, but when it goes back to A/C it still blows hot air as if the heater is on. Any suggestions?

Hi,

This could be a few different things. I need you to check something for me. When you turn the A/C on, do you hear the A/C compressor engage (click under the hood)?

If you do, then chances are it is a blend air door issue. However, this vehicle has one for each side of the vehicle, so I need to know if this happens on both sides.

Also, here is a link that you may find of interest. It discusses the most common causes of the A/C not working. Take a look through it.

Let me know.

Take care,

Joe
