The AC only starts to work at a certain temperature. Have you gone out and checked the radiator and heater hoses to see if they are hot while this is happening? It may be the thermostat needing to be replaced, and maybe the temperature sending unit might be bad.

thank you, i don't think it is problem of thermostat.... because everything will come to normal when removing battery wire and return back!!!!
