Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The problem you are having with the cooling fan can be caused by any of the following,

  • Battery Positive Voltage
  • Coolant Fan Control Module
  • Engine Cooling Fan Wiring Harness

    With the control module being the most common. In order to determine the cause you are going to need to do some testing. I have enclosed the steps in the link below, Copy and paste the link to your browser to open and view them.
