Help with the Radiator fan

[risky]

Need some help. I turned on my A/C and the radiator fan turned on like it should but now every time i turn on my car the fan turns on and stays on all the time with the A/C turned off. Does anyone have an idea whats keeping my fan on all the time. The fan does not stay on when i turn off the car. Any help would be appreciated

Bad or unplugged sensor in the COT

If the gauge in the dash cluster works the COT sensor is plugged in and working.

Sounds like the fan control module is going bad.

Exactly what im thinking.

One sensor is for the dashboard. The other is for the PCM.
If the pcm sensor is unplugged, the PCM assumes an overheat condition and runs the fan all of the time.

The Fan module can also be the culprit.
