So i figured I would call on the vast wealth of knowledge and experience here before wasting hours chasing the issue. given the symptoms, what would be the most common cause of the fan not running when it is supposed to, even though it has power and does spin when the car is started?
It has to spin more than a half turn in order for it to generate an electrical signal to the DME to know that the fan is spinning. Scan the DME and see if you have a fan fault.
