I've been dealing with an ongoing issue with my 2012 Renault Logan's radiator fan motor repeatedly failing. I purchased the car about 10 months ago, and everything was fine until the hot summer months hit (around 45°C/113°F). I noticed that the radiator fan tends to stay on for a short while even after I turn off the car. It seems like this might be by design, as there's a warning label under the hood about it.
When the fan died initially, mechanics fixed the issue by adjusting the cable and it worked for around a week. I also had a radiator leak around the same time, and they replaced the radiator. A week later, the fan failed again and it would work when they gave a knock to the motor, leading them to suggest replacing the fan motor.
Due to steep prices for genuine Renault parts and no warranty, they installed a Chinese replacement which died in a week. After hunting for a while, I found an original fan assembly at a scrapyard, but the connector had been damaged from previous attempts at fixing it and they had to do some soldering to connect it this time. This replacement failed in about 3 weeks. Not sure if this is important but a few times the fan died was when I turned the car off and back on almost immediately.
Before giving up, I'd like to know if there might be an underlying issue causing these repeated fan failures. Is there something the garages might be missing? Any advice or similar experiences would be greatly appreciated.
