oem fan question....

so i think something is wrong with my fan or the electornics to it. the fan is going off at weird times. for example, when the car is sitting all night and i start it up to drive it to work about 2 miles away the fan kicks on during the drive, and then after i turn the car off, the fan is still on. why is this happening, the motor isn’t even warm yet! recently my local shop said it was the sending unit to the fan so i had that replaced, but the fan is stil going off at weird times. what going on???


i heard that its suppose to stay on for 15 minutes after you turn your car off no matter what, and your fan comes on for like the first 60 sec. when you turn it on!
