Control Module



These engines do not use an electric fan switch per se, but rather an electronic module that can run one or both fans at two speeds.

Testing
  1. If both fans are not working, begin troubleshooting with the fan control relay.
  2.  
  3. Before servicing the vehicle, refer to the Precautions section.
  4.  
  5. Remove the fan relay from the underhood fuse panel.
  6.  
  7. Use an ohmmeter to check continuity between terminals 4 and 2.

    The circuit should be open.
     

  8.  
  9. Connect relay terminal 3 to battery (-) and terminal 1 to battery (+)
  10.  
  11. Use an ohmmeter to check continuity between terminals 4 and 2.

    Resistance should be 2 ohms or less
     

  12.  

To Test the Fan Control Module:

  1. Remove condenser fan motor connector.
  2.  
  3. Start the engine and run it at idle.
  4.  
  5. Turn the A/C switch to ON and maintain the coolant temperature at 176°F (80°C) or less.
  6.  
  7. When measuring the voltage between the fan control module-side connector terminals, check that the value changes repeatedly as indicated:

    (1) 0 volts
     
    (2) 5.6-10.8 volts
     
    (3) Battery voltage plus or minus 2.6 volts
     

  8.  
  9. If the voltage does not repeatedly change as indicated, replace the radiator fan motor and the fan control module assembly.

Removal & Installation



The radiator fan module includes a support shroud with two electrically driven motors with fan blades. The radiator fan module is fastened to the radiator. The motors, shroud, and fan blades are serviced separately.

  1. Remove the upper radiator crossmember.
  2.  
  3. Disconnect radiator fan electrical connector.
  4.  
  5. Remove the fasteners and upper clip attaching fan assembly to radiator.
  6.  
  7. Remove the radiator fan assembly by lifting upward.
  8.  

To install:

  1. Install the radiator fan to radiator. Install the retaining clip and tighten fasteners to 45 inch lbs. (5 Nm).
  2.  
  3. Connect radiator fan electrical connector.
  4.  
  5. Install the upper radiator crossmember.
  6.  

2.0L, 2.4L, 2.5L And 3.0L Engines

All models use electric motor driven, two speed cooling system fans. The fan modules include a motor support and shroud. The module is bolted to the radiator.

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Disconnect battery negative cable from remote negative terminal on shock tower and properly isolate to prevent accidental reconnection.
  4.  
  5. Remove or disconnect the following:

    Upper radiator crossmember.
     
    Fan motor electrical connector.
     
    Fasteners attaching fan module to radiator
     
    Fan module.
     

  6.  

There are no repairs to be made to the fan. If the fan is warped, cracked, or otherwise damaged, it must be replaced with only the recommended part for adequate strength, performance and safety.
