What does it mean when you turn the ignition on and the fan comes on? This is when the car is completely cold. I remember a discussion about it but can’t find it or remember the solution. Was it a bad coolant sensor?

Thanks,

wish I had that problem. mine wont turn on at all lol

better to have them come on than them n0t come on at all

ur engine coolant sensor, the one with 2 wires with the red plug might be tricking the ecu into thinking ur running hot...unplug it, the ecu should think the car is at -40 and the fans should shut off, then u know its the coolant sensor..

I will pull the red plug and see if it’ll shut off the fan. I’ll post something this weekend. Thanks for the advice.

I uplugged the coolant sensor and the fan shut off. So, I went to the Auto Zone, bought a new $17.00 (yellow plug?) coolant sensor, and replaced it.

I waited until the next day, turned on the ignition, and the fan didn't come on.

Thanks for the help Bonesmugglar,
