If the above condition is verified, perform the Repair Procedure.ġ. The vehicle operator may complain of no heat in any mode, from the front right side of the vehicle. NOTE : THIS BULLETIN APPLIES TO LEFT HAND DRIVE (LHD) VEHICLES WITH ZONE CONTROL OR AUTOMATIC TEMPERATURE CONTROL (ATC) HVAC SYSTEMS. MODELS:2001 (RS) Caravan/Town & Country/Voyager 2001 (RG) Chrysler Voyager (International Markets) This bulletin involves replacing the blend air door shaft with a new part. Here is the information from a bulletin that may apply to you as well:" The LED's or graphics will continue to flash even after the ignition switch is cycled Off and On, until a successful calibration is completed or until the vehicle has been driven about 8 miles." If the LEDs or graphics continue to flash beyond the two minute (manual) or twenty second (ATC) calibration time, it indicates that the A/Cheater control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. When the LED's or graphics stop flashing, the calibration procedure is complete. The calibration procedure should take less than two minutes to complete for the manual A/C-heater control, and less than twenty seconds for the ATC A/C-heater control. The MTC A/C-heater control Rear Wipe/Wash button light emitting diode (LED) and Recirculation button LED, or the ATC A/C-heater control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun. If equipped with the automatic temperature control (ATC) system, simultaneously press and hold the Power and Recirculation buttons on the A/Cheater control for at least five seconds.
If equipped with the manual temperature control (MTC) system, press and hold the Rear Wipe/ Wash and Recirculation buttons for at least five seconds. Turn the ignition switch to the On position. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor. The A/C-heater control module must be recalibrated each time an actuator motor or the A/C-heater control is replaced. First try to do the calibration on the heater system. If all those are satisfactory, it is posible that you have a blend door actuator problem.
John Blaine, check for a few more things like :Ĭheck to make sure that the cooling system is full,Ĭheck to make sure the engine heats up to operating temperature,Īnd make sure that all the modes on your heater operate.
