Hello I am having some issues with my ac blowing cool but not cold air. In my cabin the outside air temperature reads -- or sometimes -40. I looked at the ambient air temperature sensor in the front bumper and the sensor isn't connected to any wires. I cant seem to find any loose wires that it can hook up to. Does anyone know where these wires are or have a diagram showing where they are? This car is new to me so I dont have any history of the vehicle. Also i found an orange connector not connected to anything on the passenger side. Anyone have any idea as to what it is?

 

Do you get an outside temp reading on your dash?

If you turn the knob to full cold with a/c button pressed, it should still get cold despite the outside temp sensor reading. So I think you need to get your a/c checked out.

 

If you look down where your radiator cap is, you can see the temp sensor and see if it's plugged in with a wire coming from it.

I don't know what car you have, but I have a 2015 LX. I just checked mine out and it has the same clip or connector/plug (whatever it is) that's not hooked up to anything. Just a guess, but if it is an electrical plug, maybe it's for a smaller harness to hook up to fog light housing? But I don't even know if you have an LX as well. Mine was covered in, what felt like, old black grease and I had to rub some off to see it was orange.
