I have them and I only have the adaptive cruise control groupPretty sure that if you have BOTH the Advanced Safety Group/ACC AND the cold weather package, you get these. Just one or the other, no need for the defroster ahead of the sensor(s). IE If you don't have the Safety group, there's no need to defrost that area. And, if you have the Safety group but don't live is a cold weather area, you don't need the defroster.
Thanks @Bryce you made me go back out there and check. You are right upon MUCH closer investigation, I do have them., I stand corrected.My 2021 Jeep has the safety group, advanced safety group, which I believe includes the adaptive cruise control, and it has the cold weather package. Mine does not look like this. Do as all a favour and go back to the dealer where there will be, most likely, a simple explanation for this non-factory contraption that you have here.
Those look the same as the ones on the back window - connected to the defroster lines (pretty untechnical here) Are they the heater-uppers?I'd hate to think that FCA designed any system to look like that. It looks aftermarket, as in not neatly integrated. Are you the original owner? What do they look like from the front side?
