Inspection and Verification 1. Verify the customer’s concern by operating the climate control system to duplicate the condition. 2. Inspect to determine if one of the following mechanical or electrical concerns apply: Visual Inspection Chart Loose, missing or damaged A/C compressor drive belt. Loose or disconnected A/C clutch. Loose, misrouted or damaged vacuum lines. Broken or leaking vacuum control motora Discharged A/C system. Broken or leaking refrigerant lines. a a A leak in the vacuum control circuit may occur during acceleration (slow leak), may exist at all times (large leak), and may exist only when specific functions are selected (indicating a leak in that portion of the circuit). The vacuum hoses used in the passenger compartment control circuit are constructed from PVC plastic material. The vacuum hoses used in the engine compartment are constructed of Hytrel®. Because of the materials used, never pinch the vacuum hoses off during diagnosis to locate a leak. A wood golf tee can be used as a plug when it is necessary to plug one end of the vacuum hose for leak test purposes. 3. If the inspection reveals obvious concern(s) that can be readily identified, service as required. 4. If equipped with the electronic automatic temperature control system, go to Step 6. 5. If equipped with a manual A/C system, determine the symptom and go to the Symptom Chart. 6. If the concern remains after the inspection, connect the Rotunda New Generation Star (NGS) Tester to the data link connector (DLC) located beneath the instrument panel to carry out the DATA LINK DIAGNOSTICS test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the electronic automatic temperature control module, GO to Pinpoint Test A. If the DATA LINK DIAGNOSTICS test is passed for the electronic automatic temperature control module, retrieve the continuous DTCs and execute the Self-Test Diagnostics for the electronic automatic temperature control module to retrieve the current DTCs. Mechanical Electrical Open fuses. Blower motor inoperative. A/C compressor inoperative. Circuitry open/shorted. Disconnected electrical connectors. 7. If the self-test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics. 8. If DTCs are retrieved, go to the Electronic Automatic Temperature Control (EATC) Module Diagnostic Trouble Code (DTC) Index to continue diagnostics. 9. If the electronic automatic temperature control module cannot be accessed by the NGS, GO to Pinpoint Test A. Electronic Automatic Temperature Control Module Self-Test The EATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A NGS tester must be used to retrieve these concerns. The EATC module self-test will detect concerns in the system control functions and will display hard diagnostic trouble codes (DTCs) in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 4-32° (40-90°F) when performing the self-test. If the temperatures are C not within the specified ranges, false in-car temperature sensor DTCs will be displayed. The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated. To enter the self-test, press the OFF and FLOOR buttons simultaneously and then press the AUTOMATIC button within two seconds. The display will show a pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed. If any DTCs appear during the self-test, follow the diagnostics procedure given under ACTION for each DTC given. If a condition exists but no DTCs appear during the self-test, refer to the Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Improper Operation. To exit self-test and retain all intermittent DTCs, push the blue (cooler temperature) button. The control will exit self-test, retain all intermittent DTCs and then turn OFF (display blank). To exit self-test and clear all DTCs, press the DEFROST button. The vacuum fluorescent display window will show 888 and all function symbols for one second. Then, the EATC control assembly will turn OFF (display blank) and all DTCs will be cleared. Always exit the self-test before powering the system down (system turned OFF). Intermittent DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.

Fan Control Amplifier The fan control amplifier is located on the cooling unit. The fan control amp. receives a gate voltage from the auto amp. to step-lessly maintain the blower fan motor voltage in the 5 to 12 volt range (approx.). Fig. 169: Identifying Fan Control Amplifier DIAGNOSTIC PROCEDURE SYMPTOM: Blower motor operation is malfunctioning under Starting Fan Speed Control. 1. CHECK POWER SUPPLY FOR FAN CONTROL AMP. Disconnect fan control amp. harness connector. Do approx. 12 volts exist between fan control amp. harness connector terminal No. 3 and body ground? Yes or No Yes: GO TO 2. No: GO TO 8 . 2. CHECK BODY GROUND CIRCUIT FOR FAN CONTROL AMP. Does continuity exist between fan control amp. harness connector terminal No. 1 and body ground? Yes or No Yes: Reconnect fan control amp. harness connector. And GO TO 3. No: Repair harness or connector. 3. CHECK VOLTAGE FOR FAN CONTROL AMP. Set up Self-diagnosis STEP 4. Measure voltage across fan control amp. harness connector terminal No. 2 and body ground.
