Chrysler Sebring touring 2006 trouble code AC 48
 

I recently put her compressor in this car and then they replace the controller but my AC only blows out of defroster. Can anybody tell me where thethe door actuator or modulator whatever the heck it is is located what do I need to do to fix it? Sure would be appreciated

"Defrost" is the mode the HVAC system will go to when there's a failure. The designers figured that if the defroster worked, you could safely drive the car to get it fixed. It doesn't tell you where the failure is, but at least the mode door is working. The system is controlled by the body computer. When you set the controls on the dash, you are telling the body computer what you'd like to happen, and then the computer operates the mechanisms to cause that to occur. If that's not occurring, the problem could be with the control head on the dash, the wiring to the computer, the computer itself, the wiring from the computer to the mechanisms in the plenum or the mechanisms themselves. Those mechanisms include the "blend door", which controls the mixing of heated or cooled air to regulate the temperature, the "mode door" which steers the air to the floor outlets, the dash outlets or the defroster, or some combination of them, and the door that chooses whether air is drawn from outside the car or inside (re-circ). The point of all this is to illustrate that the system is quite complicated and there's no simple answer to your question. Diagnosis requires communicating with the computer as well as some direct observation of what is working and what is not. Throwing parts at it is a waste of time and money. If there's a problem with the operating mechanisms, it may require removal of the entire dashboard to get to to repair. The cost to repair that (if parts can be found) could exceed the value of the car.

you may want to try disconnecting the battery for 10 minutes then reconnect and try again, this will reset the modules and actuators,if this don't work,then you may have to go into your dash
