Cooling fans run all the time, Removed relays, fans stop, checked what I thought was temp sensor, was closed but fans still run, probably temp gauge, what turns fans on? Sensor? Location?

Hi:
The cooling fans are powered by the PCM. A temp sensor sends a signal to the PCM indicating coolant temp. Once a certain temp is reached, the PCM sends a signal through the fan relay which then sends power to the fans.

I need to know what size engine this vehicle has to provide sensor locations.

The A/C is unplugged also, the condenser coil took a hit and I have not replaced it, would this also cause the fans to run constantly?

I don't feel that would cause them to stay on. As far as the sensor, it should be located on the top rear of the engine. See the pic attached.

I pulled the sensor from the a/c out of the line to the condenser and plugged it in and they stopped running, Whys that? is it a pressure sensor? there no freon in the system. Matter a fact the system has no condenser.

It would normally be located in front of the Air conditioning condenser, out front of the radiator, threads into the actual a/c line, I think they're aluminum. near a beer can sized drier?, almost the size of a spark plug.

I think you are looking at the pressure switch.
