What is the reason for the Cruze fan not working?

[Mario]

The reasons for the Cruze fan not working are: 1. The relay is faulty; 2. The water temperature has not reached the required level; 3. The temperature control switch has a problem. Taking the 2018 Cruze as an example, it belongs to the compact car category, with body dimensions of: length 4666mm, width 1807mm, height 1460mm, wheelbase 2700mm, fuel tank capacity 52l, and curb weight 1240kg. The 2018 Cruze has a front suspension of MacPherson independent suspension and a rear suspension of torsion beam non-independent suspension. It is equipped with a 1.5l turbocharged engine, with a maximum horsepower of 114ps, maximum power of 84kw, maximum torque of 146nm, and is paired with a 6-speed manual transmission.

I've been driving a Cruze for several years and have also encountered the issue of the fan not working. It's usually not a major problem, but don't delay fixing it for too long. The most common cause is a blown fuse. The fuse box in the car is located next to the engine compartment. Open it up and check if the corresponding fuse is blackened or broken. Replacing it with a new one usually solves the problem. Another issue could be the fan relay. You can remove it from the fuse box yourself, shake it to listen for any rattling, or just replace it directly. If both the fuse and relay are fine, then the problem might be a faulty fan motor. Aging motors tend to get stuck, especially noticeable during hot summer temperatures. Another possibility is a faulty coolant temperature sensor. If the sensor readings are inaccurate, the fan won't start. For DIY inspection, you can use a multimeter to test the circuit. If you don't have the tools, don't tamper with it—take it to a repair shop immediately to avoid engine damage from overheating. Regular cleaning of the radiator during routine maintenance can also help prevent this issue.

Last time my Cruze's fan suddenly stopped working on the highway, which scared me so much that I immediately pulled over. The fan is crucial for the cooling system - if it doesn't spin, the radiator water temperature can skyrocket quickly, potentially leading to engine failure and costly repairs. There are usually several possible causes, such as a blown fuse needing replacement, burnt relay contacts interrupting power supply, seized fan motor bearings requiring cleaning or replacement, or a faulty temperature sensor sending incorrect signals. I've learned to do some basic checks myself - gently tapping the fan blades with a screwdriver to see if they're stuck. If they still don't move, it might be an electrical issue. A simple method is to start the engine and wait a few minutes, then touch the radiator to check its temperature. If it's scalding hot but the fan isn't running, that's a red flag. Safety first - I recommend going to a professional repair shop immediately rather than trying to save money by delaying. During summer especially, it's good practice to check if the fan is working properly before driving - developing this habit can save you a lot of trouble.

The fan not spinning is mostly due to a faulty fan motor, a blown fuse, or a bad relay. Over time, the motor can wear out and fail to rotate; the fuse may blow from excessive current; and relay coil or contact issues can prevent power flow. A malfunctioning temperature sensor may also fail to trigger the fan startup. These components need repair when they age. During inspection, prioritize checking the fuse and relay, as they are low-cost and easy to replace.
