HI Im David, you need to replace the outside air temp sensor for sure. no way the ac is going to wok if the computer thinks its that cold out.

Expert:  david craig replied 2 months ago.

you can reset the display manually by turning the ignition on, and then simultaneously pressing the MODE, FRONT DEFROST and REAR DEFROST switches. Otherwise, it will reset to the actual ambient temperature after you've driven a little bit. This is usually highway speed for a few miles, so that's why it may take your vehicle a bit longer to display it if you're just driving short distances or around town.
