Welcome, I'm Chris (aka Moose).

Here is this circuits diagram

Can you verify the fan is getting power on red/yellow and green/yellow with the key on and ground on the black/yellow?

If those are good then its the wire to the PCM, or the PCM signal to blame. The PCM pulses a ground signal to operate the fan. Can you OHM test the white/black wire to the PCM to verify its not broken? Can you monitor the PCMs command to the fan and the reading on the CHT sensor using a scan tool to see if the PCM is the cause.

If your confused on what to do now. You have already been charged the full question value. It's now time to compensate the tech that helped you. The only way I can continue to work here and help customers is by getting rated. If your not pleased yet or plan not to rate me. Let me know so I can help more, close the post, or opt out. Please let me know if you are pleased with my help.

Thanks Moose.

Hello again Chris 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 your 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. I have the option to call you if that would be better.

Thanks Chris
