I have a 91 Accord with a fan problem. When ever I turn the car off the fan kicks in for a long time. I pulled out the relay and the fans stop and then come back after about 2 hours and put the relay back in and the fan turns back on. What could be the problem

Possible that the coolant sensor is reading too high and causing the fan to stay on.

Possibly a bad relay... replace with a good 1 and see if it happens again

The original question is about 2 and a half years old. I don't think the one that asked the question still has the same problem :)
