Condenser
Description
Dual condensers are mounted behind the right and left side of the front bumper as shown. The cooling efficiency of parallel-
dual condensers is as good as or better than a single condenser mounted in front of radiator.

Radiator and Condenser Fan Controls
Description
Fan control system:
The cooling fan system is comprised of the radiator fan, condenser fan (left and right), engine compartment fan, radiator
fan low relay, radiator fan high relay, condenser fan relay, engine compartment fan relay, radiator fan resistor, radiator
fan control sensor, A/C pressure switch, fan control unit, climate control unit, and ECM.
The fan control unit controls the operation of the radiator fan and condenser fans.
It uses inputs from the radiator fan control sensor and the A/C pressure switches (A and B) in the A/C system to deter-
mine when the fans should run and at what speed.
Additionally, the temperature switch shuts down the A/C system if the engine coolant temperature (ECT) exceeds
266°F (130°C). If the pressure in the A/C system is higher than normal, pressure switch A closes and the fans will run at
high speed only. See the A/C section for the description and specifications of that function.ProCarManuals.com

2. Using an ohmmeter, measure resistance between
the A and B terminals. Replace the resistor if the
resistance is not within specifications.
NOTE: Resistance will vary with the resistor
temperature; specifications are at 68°F (20°C).

Radiator Fan Motor Test
1. Disconnect the 2P connector from the radiator fan
motor.
2. Test the motor by connecting battery power to the
A terminal, and ground to the B terminal.
3. If the motor fails to run or does not run smoothly,
replace it.
Condenser Fan Motor Test
1. Disconnect the 2P connector from the condenser
fan motor.
NOTE: The illustration shows the right condenser.
2. Test the motor by connecting battery power to the
A terminal, and ground to the B terminal.
3. If the motor fails to run or does not run smoothly,
replace it.ProCarManuals.com

Test (A/T)
1. Disconnect the 2P connector from the engine
compartment fan motor.
2. Test the motor by connecting battery power to the
A terminal, and ground to the B terminal.
3. If the motor fails to run or does not run smoothly,
replace it.
Engine Compartment Fan Motor
Removal (A/T)
1. Disconnect the 2P connector from the engine
compartment fan motor.
2. Remove the engine compartment fan relay, the test
tachometer connector, and the engine wire harness
from the engine compartment fan shroud.
3. Remove the three mounting bolts.

Fan Relay Tests
Check continuity at the relay terminals.
There should be continuity between the C and D ter-
minals.
There should be continuity between the A and B ter-
minals when power and ground are connected to the
C and D terminals.
There should be no continuity between the A and B
terminals when power is disconnected.
