DISASSEMBLY
CAUTION:
Because the automatic transaxle is manufactured
from high-precision parts, care must be taken not
to scratch or damage these parts during
disassembly and assembly. The working area should be covered with a
rubber mat to keep it clean at all times. Do not wear any cloth gloves and do not use any
shop towels during disassembly. Use only nylon
cloth, paper towels or any other lint-free material. Parts which have been disassembled should all
be cleaned. Metal parts can be cleaned with
normal detergent, but they should be dried
completely using compressed air. Clutch discs, plastic thrust plates and rubber
parts should be cleaned with automatic

2004 ENGINE COOLING
Electric Cooling Fans - Endeavor
DESCRIPTION & OPERATION The fan control module is powered from fusible link No. 2. See Fig. 1
. The PCM
judges the required revolution speed of radiator fan motor and condenser fan motor
using input signals transmitted from the A/C switch, automatic compressor
controller, vehicle speed sensor and engine coolant temperature sensor. The PCM
activates the fan control module to drive the radiator fan motor and condenser fan
motor. COMPONENT LOCATIONS COMPONENT LOCATIONS Component

CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION
The cause could be a malfunction of the fan control module power supply or
ground circuit. The cause could also be a malfunction of the fan control module or the PCM.
TROUBLESHOOTING HINTS
Malfunction of fusible link Malfunction of fan control relay Malfunction of MFI relay Malfunction of fan control module Malfunction of PCM Damaged wiring harness or connector
DIAGNOSIS Required Special Tools:
MB991223: Harness Set MB991923: Power Plant ECU Check Harness
STEP 1. Check the circuit at fan control module connector A-23 (terminal
3).
1. Disconnect fan control module connector A-23, and measure at the
harness side connector.

.
STEP 14. Check the symptoms.
Q: Do the radiator fan and condenser fan operate correctly?
YES: The procedure is complete.
NO: Return to Step 1 .
INSPECTION PROCEDURE 4: Radiator Fan and Condenser Fan do not Change Speed or Stop Radiator Fan and Condenser Fan Drive Circuit Refer to INSPECTION PROCEDURE 3: RADIATOR FAN AND CONDENSER FAN DO NOT OPERATE
.
CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION The fan controller has variable control of the radiator fan motor and the condenser
fan motor speeds using signals transmitted from the PCM. TROUBLESHOOTING HINTS NOTE: If the engine coolant temperature reaches 110°C (230°F) or
higher, the radiator fan control runs the radiator fan for up
to 5 minutes even after the ignition switch is turned to the
"LOCK" (OFF) position [the fan stops its rotation when the
engine coolant temperature decreases to 110°C (230° F) or
lower.]
