NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH REAR A/C (SALES CODE HBA).
SYMPTOM/CONDITION:
The rear A/C blower motor fan contacts a thin plastic rib inside the rear overhead A/C unit when ambient temperatures exceeds 38°C. (100° F.) resulting
in a buzzing/clicking sound.
DIAGNOSIS/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 rear A/C outlet bezel by gently separating the bezel from the headliner.
2.
Gently, pull the headliner down.
3.
Inspect the rear A/C assembly foam seal that seals the bottom of the A/C assembly to the headliner. Carefully, unfold any section of the foam seal
that may be folded over and re-secure the foam seal in its proper place. If the foam will not release from itself, the folded over portion of foam
must be cut out and removed. If the foam shows no signs of deformation, further diagnosis is required.
NOTE:
IT IS IMPORTANT TO ENSURE THAT ONLY ONE LAYER OF FOAM EXISTS BETWEEN THE BOTTOM OF THE A/C ASSEMBLY AND
THE HEADLINER. THE BUZZING/CLICKING SOUND CAN OCCUR WHEN MORE THAN ONE LAYER OF FOAM IS PLACED
BETWEEN THE BOTTOM OF THE A/C ASSEMBLY AND THE HEADLINER.
4.
Push the headliner back into place and re-install the rear A/C outlet bezel.
