no it hasn't been serviced yet since ive owned it.. i do have a bad O2 sensor, my rear one, which im putting off because i dont have emissions for awhile.. i just want my ac to start working.. now that engine is cool off, im gonna take another shot at the sensor..

also i noticed its not every time that my ac stops working that my engine temp gauge starts acting weird.. its like every 3rd or 4th time.. thats y i didn't notice it right away.

edit: i noticed this pipe/tube was loose so does anyone know wat this is for and could it be causing this.. the first pic gives u a general area, the second shows how it should be and the third shows how i found it..
