If the fuses are good, and the relay is good. The most common failure is the cooling fan control module. You could check the inputs and the outputs of the control module to verify that it needs to be replaced.

If the fuses are good and the relay is good the most common to fail is the cooling fan control module. You could check the inputs and the outputs of the module to verify it is bad. It should be attached to the cooling fans.

Hello again Dan here,

I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears you’re not pleased, or need more help.

Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help.

Thanks Dan
