Here is my issue. I bought a 2011 used that had 57k miles on it last month. Never even knew it had a display to read the outside temperature because nothing ever showed, until yesterday.

I went through the car wash and just as it started I got a warning to watch for icy conditions on the road. Thought nothing of it until I left, and my AC would not work anymore. Pulled over and noticed the display read -39, and them -40 degrees F. I was about halfway home (30 mins) and the display of the temperature went away again, but still no AC working.

Fast Forward about 12 hours, and my A/C now works again, but the temperature is still not displaying anything. I am afraid every time it rains or something it will keep doing that. Anybody have any advice/help?

Just an update. It started raining today and the sensor kicked in again at -40F. As I drove it slowly lowered by 1 degree every second until I got to about -5 Fahrenheit. When I stopped at the red light it shot back to -40 and when I started going again it slowly went down. Going to work with a friend to take off the bumper and mess with the wiring to see if its actually the sensor.

Dealership wants to charge $36 for the part and $79.99 for 1 hour (Looking at about $115), but since my A/C won't work again, I cannot really put it off for long. Will update when finished with this project.

Another update:

We just took out the black cover as said above, and turns out there was nothing but a wire hanging... no sensor... I'm not sure if it varies by car or not, but it was a green and white wire with another connector attached to it.. I am assuming that is what I plug the sensor into?

Going in to Autozone tomorrow to see if they have any, at least online it shows up as an item

The sensor never shows anything unless raining or carwash, then it would show -40. See link for picture of car and sensor location:

Update:

The part arrived in the mail today and I was overcome with joy when the part fit perfectly and plugged into the wire perfectly. I would shortly find out it wasn't that simple.

Turned on the car and it gave me the ice warning and has been stuck on -40 ever since. I drove around for a solid 5 minutes to see what it would do and got no result. Guess we will see what happens when I leave for work in the morning. More suggestions are welcome, could it be the wiring that is messed up?

Started my car this morning to go to work and was very pleased to see 52 degrees pop up on my display! Looks like it now works and what would have cost me $115 at a dealer cost me $18 and about 2 minutes of labor. Thanks everyone here for the help and assistance on solving and fixing the issue. Let's hope that I don't need to start a new thread on here again!

P.S. This forum also helped me realize why the driver side heated seat doesn't work (known car issue). Thanks again!
