The cooling fan as well as condenser fan run continually even when I don't run the A.C.They also run for a minute or so after I shut ignition off. What is the cause of this malfunction.
The sensor is giving a message that it is hot check radiator flow .

I have a 2003 MPV with the same problem. There was a recall in 2004 to replace the fan controller module, which apparently would fail regularly. I had mine replaced under the recall although there were no symptoms at the time. Now it appear that the replacement has failed, but I've already used the recall and you can only do it once. Even though your warranty is up the recall still applies if your car is of the model that qualifies. Call your dealer, and he can tell you if you are eligible. It is almost certainly the problem. I don't care how you drive or what the temperature is, your fan shouldn't run immediately after starting or run for more than a couple of minutes after you shut it off.

Check for a switch at lower part of rad. Should see a wire harness & plug on a sensor at bottom of rad. This sensor/switch also operates fan on/off according to coolant temperature. You may need to disconnect battery to get at it safely.

Try diconnecting the two wires on the temp sensor at the bottom of the radiator, you may be able to trace the wires from the fan, it that stops the fan, then replace the sensor and it should be ok
SOURCE: why is my engin cooling fan staying on?
It's not completely abnormal for some cars to have the fans stay on for a short time after the ignition is shut off. If the fans are staying on as soon as you start the car and never going off the fan relay might be sticking. Also note that the fans will go on with the a/c switch.
