DATC cools on left side only - 2003 Lincoln LS

Posted by on

  • beccaboo378 Aug 03, 2008

    I was driving my car yesterday with my husband and kids and my ac stoped blowing cold air. In fact it started blowing air so hot you couldn't put your hand in front of it. The driver side isn't really blowing hot air it is the passanger side. I took it to a mechanic and they said it was something electrical. Has anyone else had this happen to them or have any suggestions?

AC won't work on 2000 expedition front side


HVAC Blend Door Motor--under the dash has failed

You try all the air flow positions manually, from the DATC
Panel below the radio, to see which positions do not work

Then go to motorcraft parts site to see a diagram
of where the motor you need is located

You purchase the motor from Amazon (cheaper than a dealer)

All driver side controls stopped working. Intermittent at first. Now permanent.


On what the DATC Panel? (heat,a/c,etc)

You will need a scan tool, not a code reader
& factory diagnostic charts to follow, to even
get close to that problem

Dual Automatic Temperature Control Module Self-Test The DATC module self-test will retrieve on-demand (hard fault) DTCs only, it will not retrieve continuous DTCs. Continuous DTCs can be cleared when exiting the DATC module self-test. Make sure to retrieve continuous DTCs by carrying out the Dual Automatic Temperature Control Module — Retrieve Continuous DTCs procedure before clearing any continuous DTCs.
  • The DATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A scan tool must be used to retrieve these concerns.
  • The DATC module self-test will detect concerns in the system control functions and will display on-demand (hard fault) DTCs for concerns that are present during the self-test. The vehicle interior temperature should be between 4°C - 38°C (40°F - 100°F) when performing the self-test. If the temperatures are not within the specified ranges, false DTCs may be displayed.
  • The self-test can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when the self-test is activated.
  • To enter the self-test press the OFF and FLOOR buttons simultaneously and release, then press the AUTO button within two seconds. The display will show a flashing blower icon for 20 seconds, after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs present. If DTCs are present the DATC module will display "00 00" and then on-demand DTCs. Record all DTCs displayed.
  • If any DTCs appear during the self-test, carry out the diagnostic procedure. Refer to the Dual Automatic Temperature Control Module Diagnostic Trouble Code Index and follow the ACTION for each DTC given.
  • If a condition exists but no DTCs appear during the self-test, GO to Symptom Chart Condition: The DATC System Is Inoperative, Intermittent or Incorrect Operation.
  • To exit the self-test and retain all continuous DTCs, press any button except DEFROST. The DATC module will exit the self-test and retain all continuous DTCs.
  • To exit the self-test and clear all continuous DTCs, press the DEFROST button. The DATC module will exit the self-test and all continuous DTCs will be cleared.
  • Always exit the self-test before powering the system down (system turned OFF). Once the self-test is exited the ignition switch must remain ON for at least 30 seconds to allow the temperature blend door actuators to automatically recalibrate.
  • Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.
Dual Automatic Temperature Control Module — Retrieve Continuous DTCs The DATC module will retrieve only continuous (intermittent) DTCs when carrying out this procedure.
  • Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when retrieving continuous DTCs.
  • To retrieve continuous DTCs press the OFF and PANEL buttons simultaneously and release, then press the AUTO button within two seconds. All vacuum fluorescent segments will be displayed if there are no continuous DTCs present. Continuous DTCs are indicated by the presence of the degrees Celsius symbol (°C) on the DATC module display. Record all DTCs displayed.
  • If any DTCs appear, carry out the diagnostic procedure. Refer to the Dual Automatic Temperature Control Module Diagnostic Trouble Code Index and follow the ACTION for each DTC given.
  • If a condition exists but no DTCs appear, GO to Symptom Chart Condition: The DATC System Is Inoperative, Intermittent or Incorrect Operation.
  • To exit and retain all continuous DTCs, press any button except DEFROST. The DATC module will exit the retrieve continuous DTCs mode and retain all continuous DTCs.

Air conditioning blowing hot air


ok could be one of 3 things. 1 you may be out of freon. (proly spelt that wrong) 2. compresser could be bad. 3 the clutch on your compresser might not be engaging. when trucks running turn ac on and see if the front of your compresser spins or not. if it does clutch is good. but it could be that your compresser is still bad. either way i recomend you go for freon and start there. when they fill it they will tell you for sure wether or not your compresser is bad.

2003 lincoln no a/c inside the car


2003
was a new model design. I have 2002 info.

you have about 4 doors that pivot and control air flow direction either by vacuum motors or electric motors. If system fails, the default is out of the defrost ducts to keep the windshield clear.

Try this test for 2002 system.

Front Panel DATC Module Self-Test (On-demand Diagnostic Trouble Codes—DTCs)
On-demand DTCs are those that are reported by an ECU when a failure is detected while executing a diagnostic test. For the DATC module this means that all faults (hard) that occur while the module is conducting a self-test shall be reported as an on-demand DTC.
  • The DATC module self-test will not detect concerns associated with data link messages such as engine coolant temperature or vehicle speed signals. The scan tool must be used to retrieve these concerns.
  • The vehicle interior temperature should be between 0-32°C (32-90°F) when carrying out the self-test. If the temperatures are not within the specified ranges, false temperature sensor DTCs may be displayed.
The DATC module self-test through the front panel display:
  • can be initiated at any time. Normal operation of the system stops when the self-test is activated.
  • is entered by pressing the OFF and FLOOR buttons simultaneously and then pressing the AUTO button within two seconds. The display will show counts of 1 to 25 in the center of the display window. Record all DTCs displayed.
  • concludes by reporting all on-demand DTCs. Follow the diagnostics procedure given under ACTION in the DTC index for each DTC given.
  • reports individual on-demand DTCs as four-digit DTCs (less the alpha character).
  • will calibrate all the mode doors and check all analog inputs. The DATC module will only report on-demand (hard) faults that occurred while the DATC module was conducting its self-test.
  • will light all control panel display segments if no faults are detected.
  • will report individual on-demand DTCs without the °C symbol lit.
To exit the self-test, press any button. This will clear all on-demand codes from the DATC module memory. If no button is pushed DTCs will continue to be displayed.
Upon exit from the self-test the DATC module returns to operational status. The DATC module executes a hard (cold boot) reset which places the DATC system in the OFF mode.
If a condition exists but no DTCs appear during the self-test, GO to Symptom Chart Condition: The DATC System Is Inoperative, Intermittent or Incorrect Operation.
Always exit the self-test before powering the system down (system turned OFF).

2000 lincoln ls...Car dies and acts up untill it warms up


There can be several things that could cause this concern on a LS and coil packs are certainly one of them. However since the problem is more previlant when turning on climate control I would think problem may be the dual climate control valve is shorting out.The e popping up on your gear indicator is telling me that the network is getting knocked off line, kinda like your home computer rebooting during a lightning storm.
You can do a self test on the climate control,use the follwing sequence.
Front Panel DATC Module Display—Retrieve Continuous Diagnostic Trouble Codes (DTCs)
Continuous DTCs are fault codes recorded by the DATC module which have occurred during normal operation. For the DATC module this means that all faults (intermittent or hard) that occur while the module is in an operational state shall be reported as a continuous DTC.
  • To retrieve continuous DTCs, press the OFF and PANEL buttons simultaneously, followed by pressing the AUTO button within two seconds.
  • The DATC module will report all continuous DTCs to the vacuum fluorescent (VF) display.
  • The DATC module will not carry out a self-test; it will only display continuous faults codes which are stored in memory.
  • All VF display segments will light if no faults are detected.
  • Individual continuous DTCs will be reported with the °C symbol lit.
  • DTCs shall be reported as a four-digit DTC (less the alpha character).
  • Pressing the front defrost button will exit the retrieve continuous DTCs mode and clear all continuous DTCs from DATC module memory.
  • Pressing any other button (other than DEFROST) will exit the retrieve continuous DTCs mode and maintain all continuous DTCs in DATC module memory.
  • Upon exit from the retrieve continuous DTCs mode the DATC module returns to operational status. The DATC module executes a hard (cold boot) reset which places the DATC system in the OFF mode.
If you hav e code 2798 or a 2800 then I would say this is definetly your concern and I would replace the dual climate control valve. it is located on the passenger side of vehicle next to the radiator,you will see coolant hoses going to it from the heater core.
