So, im driving to work and reach over to turn down my Air Conditioning. I spin the knob as usual to lower the fan speed and everything just go wacky. my fan go's to full blast on it's own then drops down then up then down. it stoped about 10 seconds later and now I can see two separate temperatures in the top right and left corners of my display. I also lost the outside air temp reading that should have been bottom right. I turned the air back on and it works fine, fan responds as it should, temp controls work, basically everything works as it should minus the random temp's on the top and my missing exterior temp. at no time did this seem to effect any other aspect of my car. I parked at work, turned off the car, pulled the keys out and opened and closed my door to reset everything. started the car back up and everything went back to the way it should be. Only happened this one time but really, what the heck.... any ideas?
