There is two options for fans.
A mechanical option if you don't have A/C and a motor driven option if you do have A/C which is controlled by ECU.( Does yours bring up a fault code P0217 or haven't you let it get that hot?).
Here is a test you can do to check the operation of the fan (plus other functions).
Auto Active Test
DESCRIPTION
In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to
the following systems:
– Rear window defogger
– Front wiper
– Tail lamps, front fog lamps, parking lamps and license plate lamps
– Headlamps (HI, LO)
– A/C compressor (magnetic clutch)
– Cooling fan
– Oil pressure warning lamp
OPERATION PROCEDURE
1. Close hood and front door passenger side, and then lift wiper arms away from windshield (to prevent
glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON and, within 20 seconds, press driver's door switch 10 times (close other doors).
Then turn ignition switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, oil pressure warning lamp starts blinking.
6. After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
During this test the cooling fan should run for 5 seconds on Low and then 5 seconds on High on each cycle of which there is 3.
Hope this makes sense and can help.
