NUMBER:     24-006-07
GROUP:        Heating & A/C
DATE:         August 14, 2007

 

SUBJECT:

A/C Compressor Noise or Housing Damage

 

OVERVIEW:

This bulletin involves replacing the A/C Compressor with a new design and a new Condenser to compensate for revised compressor performance.

 

MODELS:

2007	(MK49)	Compass
2007	(MK74)	Patriot
2007	(PM)	Caliber

 

NOTE: This bulletin applies to 2007 PM/MK vehicles equipped air conditioning (sales code HHA or HAA) with a 1.8L, 2.0L or 2.4L (non turbo) Gasoline Engine (sales codes EBA, ECN or ED3) and Manual Transmission (sales codes DD7).

 

SYMPTOM/CONDITION:

A vehicle that is operated aggressively during cold conditions may experience damage to the A/C compressor due to refrigerant slugging causing poor or no A/C performance, possible rattle noise or compressor damage.

 

DIAGNOSIS:

Inspect the A/C compressor for physical damage to housing or rattle noise from compressor due to refrigerant slugging. If any of these symptoms exist, perform the Repair Procedure.

NOTE: Whenever a compressor is damaged internally, the suction/liquid line (liquid line assembly) and accumulator must be replaced due to potential plugging from debris in the system.

REPAIR PROCEDURE:

1. Following the procedures outlined in DealerCONNECT>TechCONNECT evacuate the A/C system.
2. Following the procedures outlined in DealerCONNECT>TechCONNECT, remove vehicle components to access and remove the A/C Compressor, Condenser, Liquid Line Assembly, and Accumulator.
3. Completely remove compressor drive belt from the vehicle and discard.
4. Flush and transfer the A/C Discharge Line (compressor to condenser) and A/C Suction Line (compressor to accumulator).
5. Following the specifications in DealerCONNECT>TechCONNECT, follow the oil fill requirements based on the components replaced and install the new Liquid/Suction Line pn 05058152AF, Accumulator pn 5189376AA, Condenser pn 68004052AB, and Compressor pn 55111555AA.
6. Install new accessory drive belt pn 04891721AB

NOTE: The new drive belt must be installed due to revised length to accommodate new pulley size.
