In July 2005, and Aug. 2008, my A/C suddenly stopped and blew only heated air. The vent function didn't work, only very hot air came through vents. The repair each time was over $1,000. It has happened again, and I cannot afford to take it in to a repair shop. I understand that it has something to do with a moveable door located under the steering column area.

Is there a diagram or some information you can provide me so I can fix it myself. I am comfortable using tools (I am a general contractor).

Thank you very much for your time and help.

Try these two things first!:
AUTOMATIC TEMPERATURE CONTROL RECALIBRATION The Automatic Temperature Control (ATC) system must be recalibrated if the battery is disconnected or loses power. If it is not, the system will not operate properly. To recalibrate the system: 1. When the battery power is restored, disconnect the electrical connector near the battery. Leave disconnected for at least 15 minutes. See Fig. 2 . 2. Reconnect the connector. Start and run the engine for at least one minute. The ATC system is now calibrated Fig. 2: Locating Connector Near Battery Used for Recalibration Courtesy of CHRYSLER CORP.

SELF-DIAGNOSTIC SYSTEM Entering Self-Diagnostics 1. Set A/C-heater control panel to display degrees Fahrenheit. Start engine (vehicle not moving) and set temperature control to 75 F. To enter self-diagnostic mode, press and hold floor, mix, and defrost buttons simultaneously. See Fig. 1 . When ATC panel display begins to blink, release all 3 buttons. 2. The display will continue to blink until it completes its tests and calibrations. Any diagnostic trouble codes stored in BCM that are related to ATC will be displayed when blinking stops. If there are no trouble codes, system will return to normal operation. 3. Trouble codes will appear on display in numerical form. Only one number will be displayed at a time. Press panel (vent) button to scroll through any additional trouble codes. See DIAGNOSTIC TROUBLE CODES table for list of codes. Exiting Self-Diagnostics & Clearing Codes To exit self-diagnostics, turn ignition off. To clear codes, disconnect negative battery cable for at least 10 minutes.
