Default 99 Honda Accord 2.3 V- Tec?

I Have a problem with my Radiator fan, They only work When I Have My A/C on. I was Told it could be the temperature sensor, does anybody know where is the temperature sensor located?

First of all there should be 2 fans in front of your car. One is for the a/c condensor the other is for the radiator. The a/c condensor fan should come on when your're idling and the radiator fan should come on when the temp gets to a certain point. You should probably check the relays and fuses first. Try interchanging relays if the fuses are all fine. Try disconnecting the radiator fan and hooking it up to 12v if it doesn't turn on it's the motor on the fan if it does there is a problem elsewhere. G/L!

there is a temperature sensor that is a switch located on the top of the thermostat housing. You should be able to follow the upper radiator hose from the radiator fan motor back to the thermostat housing; the sending unit threads into the top. HOWEVER the problem though is probably not with the temperature switch (sender) for the radiator fan but with the radiator fan motor.open the hood and start the engine. when the engine is at operating temperature turn the air conditioning on. If only one fan comes on that is the condensor fan; both fans should be on. The one that comes on is a supplemental fan to keep the radiator cool when the air conditioning is on. the other is the main cooling fan. if that's not working the chances are the fan motor is seized. It is rarely the temperature switch (sensor) though most people change that first then find out they still have the problem with the seized fan motor.hope that helps

I have to agree with my top contributor. and yet again you should have 2 fans!! If you dont then you dont even have a rad. fan and that might explain you prob.
