THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 24-008-00, DATED NOV. 10, 2000, WHICH SHOULD BE REMOVED
FROM YOUR FILES AND NOTED IN THE 2000 TECHNICAL SERVICE BULLETIN MANUAL (PUBLICATION NO. 81-170-00001).
ALL REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE ADDITIONAL MODELS AND A CLARIFICATION OF THE
SYMPTOM/CONDITION.
SUBJECT:
A/C **Honk** Or Fog Horn Sound
OVERVIEW:
This bulletin involves replacing the A/C expansion valve.
MODELS:
2001 - **2002** (JR) **Sebring Convertible**/Sedan/Stratus Sedan
SYMPTOM/CONDITION:
**Honk** or "fog horn" sound coming from the A/C expansion valve within a few seconds of A/C clutch engagement, or immediately after A/C clutch
disengagement. This sound lasts anywhere from one to three seconds and can be confused with the sound a vehicle braking system makes as the vehicle
is allowed to creep forward while at curb idle. Vibration from **the honk condition can sometimes** be felt in the passenger compartment, especially in
the steering wheel and seats. **Performing this TSB will not improve any vehicle noise conditions that last longer than three seconds.**
DIAGNOSIS:
Due to the random occurrence of this sound, it is not always possible to successfully test for this condition. Therefore, the complaint must be carefully
reviewed with the customer to avoid replacing an A/C expansion valve unnecessarily.
PARTS REQUIRED:
NOTE:
THE MOPAR REPLACEMENT A/C EXPANSION VALVE MUST HAVE A DATE OF OCTOBER 2000 OR LATER PRINTED ON THE BOX
TO BE USED FOR THIS REPAIR.
REPAIR PROCEDURE:
1.
Replace A/C expansion valve as described in the appropriate service manual.
NOTE:
REPLENISH THE SYSTEM WITH 5D15 PAG OIL MATCHING THE AMOUNT THAT WAS REMOVED DURING REFRIGERANT
RECOVERY, AND RECHARGE THE SYSTEM WITH R134A REFRIGERANT TO THE QUANTITY LISTED ON THE A/C SYSTEM
UNDERHOOD WARNING LABEL.
POLICY:
Reimbursable within the provisions of the warranty.
