I only know of the way to calibrate them using INPA. This is needed whenever a window replacement is done--and pray to J that they saved your purple LCM lens from the old windshield! This thing is finickiy...
When calibrating it, the module has to reach a certain temp range and the purple prism lens must be SECURELY fastened to the window without any bubbles. If bubbles develop, this throws off the LCM and it won't auto-wipe correctly.

Suppose to be with the "rain sensor" but I don't think replacement windshields come with this anymore.
