Body Control Module: Customer Interest
A/C - Climate Control Supplies No Hot Air
NUMBER: 24-03-99
GROUP: Air Conditioning
DATE: Feb. 12, 1999
SUBJECT:
No Warm Or Hot Air From The Climate Control System When The Engine Is Warm And The Climate Control Temperature Knob Is Set To Warm Or
Hot.
OVERVIEW:
This bulletin involves correcting the cause of a Diagnostic Trouble Code (DTC) in the Body Control Module (BCM).
MODELS:
1998 - 1999 (LH) Concorde/Intrepid
NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A MANUAL CLIMATE CONTROL SYSTEM AND REMOTE KEYLESS
ENTRY (RKE).
SYMPTOM/CONDITION:
No warm or hot air comes from the climate control system when the climate control temperature knob is set to warm or hot with an engine that has been
sufficiently warmed up. An "A/C CONTROL DOOR INPUT SHORTED TO BATTERY" DTC may be stored in the BCM (Note: This DTC may or
may not be present with this condition due to the internal feature of the BCM that self erases all stored DTCs if the proper conditions are met). Pressing
an RKE button at the same time the BCM DTC is active creates this condition. This condition can be induced even if the ignition is in the off position. In
some cases when this condition occurs, the cold air from the climate control system will only come out of the panel outlets regardless of the climate
control mode knob setting. If while the condition is present, the engine is sufficiently warmed up, the vehicle is entered using an RKE transmitter, and
the climate control temperature knob is set to warm or hot, cold air will come from the climate control system. Adjustment of the climate control
temperature knob will locate the temperature door to the requested setting until the next time the RKE transmitter is activated.
DIAGNOSIS:
With an engine that is sufficiently warmed up and the climate control temperature knob set to warm or hot, press a button on the vehicle's RKE
transmitter and verify that cold air is coming from the climate control system. An "A/C CONTROL DOOR INPUT SHORTED TO BATTERY" DTC
may be or may not be present in the BCM. Adjust the climate control temperature knob one position in either direction. If the system to goes back to
proper operation perform the Repair Procedure,
REPAIR PROCEDURE:
THIS REPAIR IS COMPATIBLE WITH DAIMLERCHRYSLER'S MOBILE SERVICE PROGRAM AND DOES NOT REQUIRE HOISTS OR
OTHER FULL SERVICE FACILITY SPECIAL EQUIPMENT.
1.
Remove the IOD fuse (circuit M1) from the junction block for approximately 60 seconds and then replace it. If the DTC "A/C CONTROL DOOR
INPUT SHORTED TO BATTERY" had been present prior to this step it should now be erased. If the DTC does not return, the repair has been
completed successfully. If the DTC returns, refer to Test 6A on pages 436 and 437 of the 1998 Chrysler Concorde/Dodge Intrepid, 1999 Chrysler
300M/LHS Body Diagnostic Procedures Manual (Publication No. 81-699-97229) for further diagnosis instructions. After performing Test 6A,
remove the IOD fuse for 60 seconds and reinstall.
NOTE:
THIS CONDITION CANNOT BE CORRECTED BY ERASING THE DTC UNLESS THE CAUSE OF THE DTC HAS BEEN CORRECTED.
NOTE:
THE "A/C CONTROL DOOR INPUT SHORTED TO BATTERY" DTC GETS REPORTED AS "RKE PROGRAM MODE ENTERED
WITHOUT REQUEST" BY THE DRB III IN VERSIONS 25.0-28.3. THIS ISSUE WILL BE CORRECTED IN DRB III VERSION 29.0. 29.0 IS
TARGETED FOR RELEASE TO THE FIELD BY 2/9/99.
