Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
Tell me more about what is going on with the fan, what was the original problem?
Do you know what the codes are? If your engine light is on then you have a code. You can get a free engine scan at any parts store for free.
Let me know what the codes are, this will give us an idea of what the problem is.
Connect a digital multimeter (DMM) to the cooling fan speed signal circuit and ground. Turn ON the ignition with the engine OFF. Manually rotate the cooling fan. Does the DMM voltage change from 0-5 volts? If so, go to step 10 . If not, go to next step.
