Let me start by kissing up thank you all for your help in the past but I am in a jam now. My fan was tested and proven to work just fine but when in my car it wont kick on fuse is fine. I was told something about a sensor but I'm not sure where it might be. I recently changed my thermostat and it's not there you guys are life savers please help and thank you in advance.

It is the fan switch (I think its also called the coolant temp sensor) and it is located on the thermostat housing. I replaced mine two weeks ago, and it was $40 through Honda. Try a local autoparts store first, since its not like the Honda ones are high quality.

On my Integra, the sensor is on the top hose, where the thermostat is. The sensor has a wire plugging into it, so you cant miss it.

Coolant sensor

Did replacing the sensor fix your problem?

I have the same issue though I replaced the sensor and the fan still does not kick-on. I am getting an error code 6, which is a defective/unplugged circuit/sensor. I have tested about half the wires, but the remaining ones are getting a bit difficult to locate. I also replaced the relay even though I knew the one in the car wasn't bad.

I am really at a loss now, though I guess I will finish checking the circuit, there must be a short somewhere.

This is becoming a serious issue for me as the weather gets hotter, and this car has had enough overheating issues in the past. Luckily it is only driven about twice a week.
