I checked fuse & relay cluster box it's not getting any voltage to the relays.
One fan is controlled by the ac controller then other is controlled by the temp sensor and the computer
It may have a thermostat to send power to the relays. Try it with the engine warm.
SOURCE: ac not working
I had the same problem with the over temp sensor on the compressor. I had it repaired at the dealer for $200.00 plus. I just had the same problem reoccur. This time I bypassed the switch myself.
There is a small wire harness that runs from the compressor above the radiator, inside there are three wires. After determining which ones to jump " two smaller gage blue" the AC system works fine in all modes.

check the wires to the clip on the horn they rust and then there no connection

The thermostat is at the back near the transmission,just to let you know the water pump you have may be the one that has the plastic propellor they known to always fail.

Hi there: The engine coolant temperature sensor provides an input voltage to the PCM. As the coolant temperature varies, the sensor resistance changes resulting in a different input voltage to the PCM. When the engine is cold, the PCM will demand slightly richer air/fuel mixtures and higher idle speeds until normal operating temperatures are reached. The engine coolant temperature sensor is also utilized for control of the cooling fan.
The engine coolant temperature sensor is a variable resistor with a range of -40 degrees F-265 degrees F (-5 degrees C-129 degrees C).

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.
Trouble Code: P1491
You PCM does not sense current to radiator fan when it turns it on. Is the fan coming on or not? Usually not when you have this code. Problem can be with the fuse, relay, wiring or fan itself. First check the fuse. If good, next try swapping the relay with another one in the engine compartment relay box, such as the horn relay.
Let the car warm up and see if the fan will come on. If yes, get a new relay. If not, either use a test light to see if there is voltage at the fan connector when the engine is on and hot, or else test the fan motor by hotwiring it to the battery. If none of this works, please get back to me for how to troubleshoot the wiring.
Radiator Fan Control Relay Circuit Malfunction
Possible Causes:
Radiator fan control relay circuit is open or shorted to ground
Radiator fan control relay circuit is open (test power to IGN)
Radiator fan control relay is damaged or has failed
PCM has failed
