2014 63s Washer fluid warning/Ambient temp sersor

A few months back my ambient air temp sensor got hit and stop working --- or -40. Living in NYC I waited for a warm day/oil change. I also notice my washer fluid would not warn me when low or even empty. I was like that will wait till spring.
I installed new ambient sensor turned ignition on washer warning came on ... sensor took some time to report correct temperature since it was inside the house. I remove the sensor reinstall the old sensor ign on no washer alert. I then reinstalled the new sensor finish my oil change and the washer alert came on that I was low.
Seem like the washer fluid sensor and the ambient sensor are someone working together.

Is it possible because our windshield washer tank is heated that it turns on the heater based on what the ambient temp reads?

I did it again today when doing my trans fluid and and no warning...when the bad ambient. I am finally adding washer fluid to the tank.
These are the items that will make you go mad. I could see my myself trying to get to the washer tank.
