Appreciate the imput guys. You may be on to something Big Z. I had a navigation system installed (eclipse) and a backup camera intergrated along with it. They ran a wire from the camera control up and merging onto a wire on the rearview mirror. This was done in order for the camera to come on automatically when put in reverse. Are you saying the the rearview mirror could be the cause of this problem. It is definitely not the weather. I am in Charleston SC, and the it has been in the upper 60's most of the week. Says ice possible everytime I start the vehicle. Thanks again. I would welcome any additional opinions or knowledge on the subject.
