Cooling fan trouble shoot?

[bassrebel]

Hey Guys!

I recently had an engine hot warning message while idling waiting for takeout food. After I started driving it back home the message went away, which lead me to suspect that the water pump and thermostat were not the culprits.

I installed Bimmerlink on my phone and ran the error messages and there were no error messages about water pump, so I was relieved. I also put the water pump in the Bimmerlink dashboard and I can see it running, which is good!

Now, I have seen that the cooling fan is not activating... not when the car was warm, not when I turned AC on, or even the heater.

Is there a way of troubleshooting the cooling fan to see if I can make it work again before buying a new one?

Thanks!

So I went ahead and purchased a new fan/shroud combo... I’ll report back if that ends up working =]

check the thermostatic switch and relay first... Apply 12 volts to the fan to see if it runs...THen you can eliminate the fan

Soooo I got my fan today and as I’m detaching it I realized it wasn’t working because it was impacted by a piece of trim... took the trim out, put everything back together and tested the car and it’s working perfect, no overheating issues, temps are fine, water pump not overworked

simple fix! Good Job
