Hi There, I'm Clayso a certified master automobile technician with 30 years of automotive repair and diagnostic experience.

From your description most likely the A/C triple pressure switch is open internally and keeping the fans on. At the A/C pressure switch ground the blue/black wire and see that the fans shut off, you can also ground the light green wire and turn the fans off.

I hope this information is helpful. If you have any questions let me know. You can reply back to me through this thread at any time.
