When my windshield was frozen and had ice and other times not frozen, I’m seeing my de icing wiper button is like dis engaged and can’t press it, anyone know why?

From the manual:
“This feature can only be activated when the vehicle is in Park, and sufficient washer fluid is in the washer reservoir.”

“WARNING: Operating the washers in cold weather can cause the fluid to freeze on the windshield, potentially obscuring your vision and causing a collision. Use the windshield heater to warm the windshield to reduce the possibility of the fluid freezing.”

“CAUTION: Do not operate the washers when the fluid reservoir is empty or frozen. This can cause the washer pump to overheat and fail.”
