I have a 2013 juke sl and I have an issue that the cooling fan wont come on at all.
Not with the ac on or after driving around. It even over heated once when I was sitting still.
I have changed the relay and the fan control module and I've jumpered the fan and it runs. I also have voltage coming to the relay socket .
The 50 amp fuse is good.
I'm trying to figure what else it could be.

The cooling fan might work but once it gets hot. It could stop running. Internally shorting or heat soaking. There is a recent thread on someone diagnosing this.

Wade, I'm the one with the heat soak issue. I found all my connections good even got the family to run, in one speed. There are two separate motors in the fan. You have to test each one. I only got mine to fail once the engine had been running for a while with all the bodywork on and hood closed. Drive it around and came home, no matter what I couldn't get the fan back on. Granted, at this point everything was way too hot to put direct 12v to the fan directly. The best I can figure is heat soak is changing the internal resistance or capacitance of the motor and it is acting like it is blown. I will do some testing today against the good fan before I swap them out today.

That usually indicates your water pump has failed. If temperature goes up when idle but goes down when there's airflow over the radiator core, there's low or no circulation of fluid through the system. could still be radiator fan related.

 

[Macgyver]

No air flow it will over heat. Not like the cars of years past with fans that rotated with the engine.

It could be a sticking thermostat tho.

I did a resistance check on the fan motors of both the old fan and new fan. The old fan low speed or upper connector read between 14-18 ohms. It moved around, but there was definitely resistance. The high speed was completely open. No connection internally. The new fan read zero ohms resistance on both fan motors. This can give you another tool to check your stuff with and hopefully find the culprit.

H9Z711,
The fan never comes on, when the engine is hot or with the ac on. I did put voltage to both plugs and the low speed and high speed came on. I'm afraid it could be the IPDM.

Go through the FSM checks. Start with the self test. It won't likely work based on what you are saying, but it will refer you to the troubleshooting steps for the Control module, relay and give you pinouts for testing continuity between IPDM and the control module. That is what I followed, just make sure when it tells you to check for voltage at the output of control module you check the module and not the connectors like I did initially. I felt like such an idiot once I figured out what I did wrong. Good luck and keep us posted.

 

[Vector W8]

Is the temp sensor good?

 

[H9Z711]

Vector,
It is not likely the temp sensor as the fan will not come one even with the A/C on. The A/C switch automatically engages the low speed fan to get air movement across the condensor for proper operation. Looking back over all the posts Wade's issue is likely a lack of continuity between the IDPM and the fan control assembly, a bad IDPM, or bad continuity between computer and IDPM. Hopefully he is able to troubleshoot it and let us all know. More information we all have the better it is to maintain these headaches,..... I mean cars.

 

[Wade226]

Well I did the self test and as expected the fan didn’t come on. But I did figure out that the plug coming into the fan control module didn’t have any fire so I lost power some where from the source of power to the module.

 

[Macgyver]

Any way to splice in power instead of replacing the IDPM ? Some other source that comes on with the AC compressor?

 

[Wade226]

I don’t think it’s the IDPM. The big plug that connects to the fan control module with 3 terminals, the positive terminal is dead #3.
Which is supposed to be hot with ignition on. Terminal #2 which is a small wire is the one that the signal comes from the IDPM.
So the fan module is not receiving constant power with ignition on. I have to find out where the power for the fan module comes from. The fan relay is on a different circuit which is good

 

[H9Z711]

Do you know where the power is supposed to originate from going to the power control module? Is it coming from the fuse and relay box? That wouldn't be too long a run. Wondering if there is just a bad connection at a terminal splice. Keep us updated, I am very interested in the resolution on this matter.

 

[Rickya]

Have same issue as @Wade226..did you find reason why module didn't get power

Hi Guys
I got some problems with my electric fan
Does the electric fan of a 2013 Nissan Juke got brushes or is it working with magnet field
