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.

DESCRIPTION In conditions of high humidity and high ambient temperatures, fogging may develop on the lower exterior por- tion of the front windshield. Fogging occurs when the A/C is on, and the dash, floor, or dash/floor vents airflow modes are selected. When these airflow modes are selected, small amounts of air may flow from the defroster vents. Fogging occurs when the temperature difference between the interior and exterior increases. Customers having this concern should have their vehicle repaired using the following repair procedure. REPAIR PROCEDURE 1. Set fan control dial to speed 3. 2. Set airflow mode selector to dash vents mode. 3. Place a sheet of 8 1/2” x 11” paper on center of dashboard over defroster vents. 4. Turn ignition switch ON and observe paper. – If paper starts to flutter, proceed to Step 5 and perform repair procedures in this service bulletin. – If paper does not flutter, do not perform repair procedures in this service bulletin, refer to Workshop Man- ual (Section 07) for further troubleshooting. 5. Record customer’s radio pre-set stations. 6. Move both front seats to most rearward position. 7. Fold both front seat backs backward (flat position). 8. Open glove compartment.Remove glove compartment being careful not to break hinges (shown below). 1167d 10. Remove damper clip string from right side of glove compartment. DAMPER CLIP STRING

1. Recover the refrigerant with a Recovery/Recycling/Charging System. 2. Remove the dashboard lower cover, the knee bolster and the glove box. 3. Remove the ECM. 4. Remove the ABS control unit and the radiator fan control module together with the bracket, then remove the TCM. Remove the security control unit. 5. Disconnect the connectors from the power transistor, blower motor high relay, evaporator temperature sensor, blower motor and the heater sub- harness, then remove the blower motor and heater subharness connectors from the brackets. Disconnect the passenger’s airbag harness clip. 6. Remove the wire harness clips, the three self-tap- ping screws and the pipe cover. 7. Remove the expansion valve covers, then disconnect the suction line and unbolt the expansion valve from the evaporator. NOTE: Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination. 8. Disconnect the drain hose, and remove the seven self-tapping screws. Then pull the evaporator out of the front passengers side to remove it. NOTE: Be careful not to damage the evaporator fins when removing the evaporator. 9. Install in the reverse order of removal. Make note of the following items. If you’re installing a new evaporator, add refrigerant oil (ND-OIL 8). Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil (ND-OIL 8) before installing them. NOTE: Be sure to use the right O-rings for HFC134a (R-134a) to avoid leakage. Be careful not to damage the evaporator fins when installing the evaporator. Install the expansion valve capillary tube with the capillary tube in contact with the suction line directly, and wrap it with tape.
