I have a 92 honda accord ex cpe with 140k miles on it. Recently the car has been overheating when driving. I checked under the hood and replaced the thermostat since it was bad but the car overheated on me 4 blocks from my house. I checked under the hood again to find the smaller fan not working. I bought a new one and it works only when I turn on. When I turn the car off, the larger of the 2 fans runs but never while on. Can someone help me out?
