Chrysler Repair: Air intake module, fuse panel, air injection

Question
I have an  05 sebring with a 4 cylinder.  The problem I have is that there seems to be something draining the battery when parked.  I checked the car and noticed that there is a motor that is kicking on and off when parked.  I was told it is the air itake module.  it is in front of the engine with a couple plugs that go into it and a hose.  this is below the inatke manifold itself.  This is what kicks on and off when the car is parked and no keys in the ignition.  What do you think I should change out first?  If you need more info please call me at .  thank you for any help you can give me.

Answer
I would not recommend changing anything out before there has been some sort of diagnostic performed. The motor you hear running is the Air Injection Pump. It is controller by the PCM through a sensor and relay. There is also a fair bit of wiring involved. Guessing at which component is failing is costly and time consuming. Until you can get it diagnosed open the fuse panel under the hood and remove fuse #7. This fuse supplies power to the relay which controls the pump. That should stop it from running and killing the battery.
