The temperature charge also A/C not working. Sometime while the temperature was working A/C was working. I did scan the car it appears three sensor. I have changed the coolant sensor what ever. I could not identify the problem. If you know problem respond me. My friends if you can tell which sensor have to change it or another problem. Thank you.

I am sorry, do you mean the temperature gauge on the dash is not working? If so the coolant temperature sender on the rear of the cylinder head feeds that signal to the computer.
From your description I would check the wiring at the sensor connection and back to the power train control module. The wires break right inside the connectors or in the wiring harness and you get no signal. If you have a scan tool put it on live data and watch the coolant temperature PID while you move the connector and wiring around. If it suddenly works you are near the problem.
