Adaptive windshield wiper?

[Mikes578514]

I was at the glass repair shop today due to a stone chip in my 98 ram 1500. The estimator said my windshield had a rain sensor and a humidity sensor, I know that the automatic wipers do not work. I got home and went through the settings screens and couldn’t find how to turn them on.

in order to get the sensing wipers to work is it just a ECM update or what else might be needed or wrong? Or am I missing something in the settings

thanks
