Temperature display goes to a negative number & "ICE"
The outside temperature reading will go to a negative number at times, as low as -15. When it does this, if the air conditioner is on auto, it will go off. It has to be a sensor somewhere going crazy, but where is it?
a 6ya expert can help you resolve that issue over the phone in a minute or two.

There are two fuses one in the right I/P junction block an one in the left I/P junction block ! The right is marked DK / RKE 10amp fuse. The left is marked A/C / CRUSE 10amp fuse ! I don't think these are the problem ! These fuses supply power to the microprocessor in the driver information center . According to my service information the microprocessor supply's power to the ambient air temperature sensor an to the compass.
This mode displays an 8 point compass heading on the left hand side of the DIC. The compass will display the current vehicle direction relative to one of 8 compass headings using N, NE, E, SE, S, SW, W, and NW for the readout. The ambient temperature displays on the right hand side of the DIC. If the ambient temperature is below 3?°C (37?°F), the temperature reading will toggle between displaying the outside temperature and the word ICE for two minutes. If the temperature is less than minus 40?°F for more than 2 seconds, OC will display. If the temperature is above 140?°F for more than 2 seconds, SC will be displayed. If OC or SC is displayed DTC's will be set. For compass calibration and compass magnetic variation adjustment refer to Electronic Compass Calibration .
The outside air temperature indicator's displayed temperature can be recalibrated. Press and hold the reset select button for 10 seconds . While you continue to hold the button, the display will scroll through temperature settings from +3 to -3. When the desired correction value appears on the display, release the button, and the recalibrated outside air temperature will be displayed. Each time a desired correction value is entered, it replaces the previous value. Give that a try mmkayyy:)
Make sure coolant level is as it should be. If level is low look for evidence of leak(s). Top off fluid if necessary. The engine coolant temperature sensor is a very common issue with these vehicles and may be the cause of your issues if no leaks are found. Also a faulty thermostat cans cause the sensors to read voltage high but most likely a sensor issue. The sensor is a potentiometer (variable resistor). The computer sends 5v through one of the wires this voltage goes through a resistor which will vary the voltage based on temperature sensed by the engine coolant temperature sensor. The sensor has a negative temparature coefficient meaning the resistance will go down when temperature is high and up when temperature is low. The less resistance the more of the 5 v gets back to the computer. The PCM detects this high voltage and set the check engine light on warning you of an issue. Whe this sensor goes bad it is usually accompanied by temperature gauge fluctuation or erratic operation and the cooling fans run long or all the time even though the vehicle is cold. Hope this helps.
If so, you might have your speed warning set too low. These cars have 2 speed warnings. Speed warning 1 resets each time you turn off the ignition. Speed warning 2 is stored in the memory. It sounds like you have a problem with no.2, but it's weird because I'm pretty sure the warning has to be set to at least 3mph. Your owner's manual shows you how to set the speed warnings under "controls and equipment - driver information displays."
The temperature reading is just the ambient (outside) air temperature.
The ambient air temperature sensor is bad or has a connection/wiring problem. It is not blowing cold air because it thinks the outside air is less then 35degrees. When the computer sees outside air less than 35 it disables AC so that ice will not form inside the vehicle and in HVAC system. The sensor is directly behind the front grill. You might be able to check it for connection/corrosion/frayed or damaged wires. If no evidence of this I would replace it.
