SPECIAL POLICY: A/C HIGH SIDE SERVICE FITTING. Buick Skyhawk 1988

For 1990-2009 cars

# SPECIAL POLICY: A/C HIGH SIDE SERVICE FITTING

#### MODELS AFFECTED: 1988 SKYHAWK WITH AIR CONDITIONING

General Motors has determined that some 1988 Skyhawks equipped with air conditioning are missing the high side service fitting. This affects diagnostics of the air conditioning system if service is required.

Buick's concern in this instance is not with the operation of the air conditioning or with any other vehicle system. Rather, this bulletin addresses procedures dealer service technicians will follow when diagnosing random air conditioning complaints in the future.

#### CONDITION

For 1988 Skyhawk production, the orifice tube in the air conditioning system was moved; however, the High Side Service Fitting was not relocated on early built vehicles with the consequence that both the High Side and Low Side Service Fittings were on the low pressure side of the orifice tube.

If analysis of an air conditioning refrigeration complaint requires reading high side pressure in early built 1988 Skyhawks with 2.0L (VIN Code "K") engines, it will be necessary to replace the Hose Assembly - A/C Compressor and Condenser, with a new assembly, Part Number 22545477. The new assembly incorporates a Shrader-type valve fitting for reading the high side pressure.

#### SPECIAL POLICY ADJUSTMENT

General Motors will replace the Hose Assembly - A/C Compressor and Condenser at the time first use of the High Side Service Fitting is required to diagnose an air conditioning refrigeration complaint. This special policy adjustment is effective through the last day of September, 1994.

This "Special Policy" bulletin should be filed in the three ring binder previously furnished to the dealer by General Motors.

#### VEHICLES INVOLVED

1988 Skyhawk models with Air Conditioning built from the start of 1988 model year production through and including VIN JK418980.

#### REIMBURSEMENT

Customer claims for reimbursement on previously paid repairs are to be submitted according to the instructions included with this bulletin. Owners must submit ORIGTNAL DOCUMENTATION that reasonably confirms the amount of unreimbursed repair expense, a description of the repair, the date of the repair, ard the person or entity performing the repair.

Reimbursement shall be only for the reasonable cost of parts and labor to replace the Hose Assembly - A/C Compressor and Condenser, including discharge/charge of the A/C system.

To receive reimbursement for unreimbursed repair expense due to a previous replacement of the Hose Assembly - A/C Compressor and Condenser, for the purpose of reading pressures at the High Side Service Fitting for diagnosis of A/C refrigerant system complaints, eligible owners must submit claims to an authorized Buick dealer no later than September 30, 1994.

#### PARTS INFORMATION

Parts are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a "C.I.O." order with NO special code, but on an advise code (2).

Part Number Description Quantity/Vehicle ----------- ----------- ----------------- 22545477 Hose Assembly - A/C Compressor 1 and Condenser

5887997 Seal, Suction Discharge Ports 2 (0-Rings at A/C Compressor)

Refrigerant-12 As Required

The following seals (0-Rings) are shipped already installed on the Hose Assembly - A/C Compressor and Condenser. However, if missing, use:

3094216 O-Ring Connector - Refrigerant Max 1, If Req'd (at A/C Accumulator outlet fitting)

3094214 Seal, A/C Condenser Fitting (0-Ring) Max 1, If Req'd (at condenser end of Discharge Line)

#### SERVICE PROCEDURE

To replace the Hose Assembly - A/C Compressor and Condenser, refer to the 1988 Buick Skylark/Skyhawk Service Manual, Sections 1B and lBl, for proper service information.

If the Hose Assembly - A/C Compressor and Condenser has been previously replaced with a correct part, a pressure fitting will be found on the high pressure "vapor" line which runs between the A/C Compressor and the Condenser at a point near the Condenser inlet (see illustration). In that case, replacement of the Hose Assembly - A/C Compressor and Condenser under the terms of this Special Policy would not be necessary.

When taking low side pressure readings, use the Shrader Valve fitting at the Accumulator Assembly only. Do not use the extra fitting near the condenser on the Tube Assembly - A/C Evaporator (pipe conveying liquid Refrigerant-12 from the condenser to the evaporator). See illustration.

#### WARRANTY CLAIM INFORMATION

When performing the repairs outlined in the Service Procedure of this bulletin, submit a warranty claim for credit, as follows:

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
