What will cause the cooling fan motor to not work on a 2014 Malibu LTZ 2.0 L engine ?

The engine is over heating because the fan is not working. I know for a fact that the fuse, relay and the fan motor are good. When I turn on the air conditioner the drivers side fan comes on but the passenger side fan doesn't come on at any time. When I hot wired the passengers side fan it will work. It must be some kind of sensor or similar part. I need a wiring diagram of the electrical circuit of the fan motors for the passenger side & drivers side circuits.

Wiring short--failed connection --the coolant sensor controls fans ie a/c goes on secondary fan comes on -- https://www.google.com/search?rlz=1C1CHBF_enUS812US812&q=2014+malibu+wiring+diagram&tbm=isch&source=univ&sa=X&ved=2ahUKEwiM0Y_X_rvjAhUrn-AKHfY4A5AQsAR6BAgFEAE&biw=1600&bih=789 or sign into autozone.com and search their diagrams

I agree with the others. It appears you two coolant temp sensors, one is in the water outlet, in the picture. #9 at top right, you can see the plumbing that goes down to water pump. The other one is in the radiator. Sometimes with sensors, a bad signal is worse than no signal at all. No signal and the computer may use a default signal which is better than bad signal. Some makes and models, if you turn on the ac the fan will run. If you unplug the cts, the fan will run. Now, whether one or both fans should run?

Testimonial: "Here is what's been done, I took the coolant temperature sensor plug in off with the engine running & the drivers side fan came on but the passengers fan didn't come on but when I turned the motor off the drivers side fan kept running, had to remove the fan fuse to stop the fan from working. Do you have a pictorial view for the radiator coolant switch that you were talking about. Send the one with the radiator coolant switch similar to the picture you sent here that has the sensor near the water pump if u don't mind, Thanks"

    I disconnected the plug in to the coolant sensor & drivers side fan came on but the passengers side didn't come on while the motor was running

  • sherman north Aug 03, 2019

    no check engine light was on prior to disconnecting the coolant plug in

    PERHAPS THE FAN IS BROKEN , CHECK IT MAYBE YOU NEED TO REPLACE IT

  • sherman north Aug 04, 2019

    when the fans are hot wired they work

  • RAFAEL Aug 04, 2019

    TO CHECK FANS TURN THE CAR ON THEN TURN ON A/C FULL BLAST THEN THE FANS SHOULD START TO COOL OFF THE RADIATOR .

    the drivers side fan works the AC is turned on but when it's off it doesn't work

    would it give a coolant sensor check engine code

  • Scott Campbell
    Scott Campbell Aug 03, 2019

    Maybe- some give a code if theres a complete fault (broken wire). But if the sensor is just sending the wrong signal, the computer wont know.

  • sherman north Aug 04, 2019

    ok, are there any more sensors in the circuits that controls the fans besides the coolant sensor, if so, do you have a picture of the circuits ? There are no check engine codes.

  • sherman north Aug 06, 2019

    Scott, it was the coolant sensor,ti was hidden down in the motor, hard to get to but it's fixed now, it has a u shaped clip that holds it, thank you here is an image of the coolant sensor below

  • sherman north Aug 06, 2019

    this coolant sensor is located the drivers side of the motor

I've had this problem before too...first check to see if your fan can be rotated by hand (make sure the car isn't running while checking). If you can't spin the fan by hand, then you need to replace the fan. The cooling fan has a 40A fuse in the fuse box under the hood (driver's side). If your fan has siezed, it will trip this fuse too.

Where is the cooling fan switch located on my 2005 malibu 3.5liter v6


Cooling fan switch ? The cooling fans (2) on that motor are controlled by three relays . A coolant temp. sensor gives temp info to the PCM - engine computer .
During high speed operation the PCM supplies the ground path for the cooling fan 1 relay through the low speed cooling fan relay control circuit. After a 3 second delay, the PCM supplies a ground path for the cooling fan 2 relay and the cooling fan S/P relay through the high speed cooling fan relay control circuit. This energizes the cooling fan 2 relay coil, closes the relay contacts, and provides a ground path for the left cooling fan. At the same time the cooling fan S/P relay coil is energized closing the relay contacts and provides battery positive voltage from the cool fan 2 fuse on the cooling fan motor supply voltage circuit to the right cooling fan. During high speed fan operation, both engine cooling fans have their own ground path. The result is a parallel circuit with both fans running at high speed.
The PCM commands Low Speed Fans on under the following conditions:
• Engine coolant temperature exceeds approximately 106°C (223°F).
• When A/C is requested and the ambient temperature is more than 50°C (122°F).
• A/C refrigerant pressure exceeds 1 310 kPa (190 psi).
• After the vehicle is shut off if the engine coolant temperature at key-off is more than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.
The PCM commands High Speed Fans on under the following conditions:
• Engine coolant temperature reaches 110°C (230°F).
• A/C refrigerant pressure exceeds 1 655 kPa (240 psi).
• When certain DTCs set .

Radiator fan not working when car heats up fuses are all good for a 2002 chevrolet malibu

Malibu overheating


Your cooling fan is not coming on when engine is warmed up. Could be the fan motor is broken. You can check this by checking the fan operation when the a/c is on and engine is warmed up. Look at the fans and see if one or two are on. If both are on then your temperature relay is unplugged or broken. If just one fan is on then most likely the fan that's not on is broken.

1999 Malibu Cooling fans don't come on. Country driving is fine. City driving and a few stop lights and it over heats. Temp Gauge works fine. If I un plug the sensor then fans come on but Tranny and Engine...


country driving at high speeds keep engine air cooled. but in city there is not much air to cool the engine. check the sensor for the fans. relay for fans must be ok, cause you said if you disconnect sensor then fans run. replace fan sensor. also make sure there is a proper amount of coolant in system. (do this first).

I have 2003 grand cherokee with 140000 miles that overheats at idle. as soon as i start moving again, the temp goes back to normal.


You have two fan's on your truck, 1 is a fan clutch runs with the drive belt, 2 elec fan motor, with test light and engine running at normal temp, just a little bit above 1/2 way on your temp gauge check voltage at elec. cooling fan harness if you have voltage at one of the two wire's and fan don't turn on, bad cooling fan motor, on the fan clutch after you check voltage at elec. fan motor turn engine off, with your hand spin drive belt fan if it spin's freely bad fan clutch, replace it.Also check cooling level.Hope this was very helpful
