T FUSE DESCRIPTION Main Fuse Block The main fuse block is located on the right side of the engine compartment and contains nine fuses and two relays. -1 Fuse Box Fuse block No.1 is located above the dead pedal of the driver side. The fuse box cover shows the speci- fied fuse locations. A circuit breaker is included in the fuse box to protect the heater blower motor circuit. Fuse block No.2 is located to the side of the battery in the trunk compartment. 45UOTX-016 REPLACEMENT Caution Determine and correct the cause of a burnt fuse before replacing it. If the fuse is replaced before doing this, it may burn again. Plate type 1. Disconnect the negative battery cable. 2. Replace the failed fuse with the fuse puller. 3. Reconnect the negative battery cable. Cartridge-type 80A fuse (Black) 1. Disconnect the negative battery cable. 2. Remove the fuse block mounting nuts, and remove the service cover. 3. Remove the fuse installation bolts, and pull out the fuse. 4. Install the new fuse and the fuse installation bolts. 5. Install the main fuse block. 6. Reconnect the negative battery cable.

TROUBLESHOOTING u TROUBLESHOOTING GUIDE I Symptom Blower motor does not operate Reference page Below Magnetic clutch does not operate I U-7 Condenser fan does not operate e Symptom: Blower motor does not operate I U-9 Insufficient cooling No cooling Intermittent cooling Normal operation of blower motor Blower motor speed is controlled by the fan switch and a resistor in the blower unit. When the fan switch L is in the OFF position, the motor ground circuit is open and the blower motor does not operate. When the switch is in the first (Low) position, current flow from the blower motor is restricted by the three resis- tors in the resistor, and the blower motor turns at low speed. Changing the fan switch to the second (Mid), third (high), or fourth (Super-high) position causes the cir- cuit resistance to decrease, and the blower motor speed becomes correspondingly faster. I l U-10 (-1 (rn) I I I RESET BUTTON FUSE BLOCK Step 1 1. Check the circuit breaker. 2. If the reset button is not out, go to Step 2. 3. If the reset button is out, check for a short circuit in the harness. Repair as necessary; then depress the reset button to reset the circuit breaker. circuit breaker HEATER Step 2 1. Turn the ignition switch to ON. 2. Turn the fan switch to the fourth position. 3. Measure the voltage at the A terminal wire of the blower motor connector.

TROUBLESHOOTING u 7- Symptom: Magnetic clutch does not operate I Normal operation of magnetic clutch The PCME controls the operation of the condenser fan and magnetic clutch, depending on engine load. (Refer to section F.) The magnetic clutch is supplied with battery positive voltage as follows: 1. The ACS and fan switch are turned on. 2. The PCME receives a signal that the ACS and fan switch are on and creates a ground circuit. 3. The A/C relay is magnetized and the contact is closed. 4. Battery positive voltage is applied to the magnetic clutch and the clutch locks. WIPER 20A AD FAN 20A FUSE BLOCK MAIN FUSE BLOCK Step 1 1. Check the following fuses.
