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

Technical Descriptio
n
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 radiator fan motor. Malfunction of condenser fan motor. Malfunction of fan control module. Malfunction of PCM. Damaged wiring harness or connector.
Diagnosis 1. Disconnect fan control module connector A-23. See Fig. 7
. Measure for
voltage between terminal No. 3 (harness side of the connector) and ground
when ignition switch is turned to the ON position. If battery voltage is not
achieved, go to next step. If battery voltage is achieved, go to step 8 .
2. Check fan control relay. See FAN CONTROL RELAY under
COMPONENTS TESTS. If fan control relay is okay, go to next step. If fan
control relay is not okay, replace it and retest.
3. Check the MFI relay. See MULTI
-PORT FUEL INJECTION (MFI)
RELAY
under COMPONENT TESTS. If MFI relay is okay, go to next step. If
MFI relay is not okay, replace it and retest.
4. Check for harness damage in Black/Yellow wire between fusible link No. 2
and terminal No. 4 of fan control relay connector A-10X. See Fig. 8
. If wire is
okay, go to next step. If wire is damaged, repair or replace as necessary and
retest.
5. Check for harness damage in Blue wire between terminal No. 2 of fan control
rela
y connector
A-10X and terminal No. 3 of fan control module connector A-
