Yeah, it was sunny when it first started to not work. I've tried activating it multiple times since in every lighting condition (at night, indoor light, shade, etc) and at every speed (highway, standing still, crawling, 35mph, etc). I just taped a dark piece of paper to cover the painted part of the front spoiler in front of the sensor since it's white, but no luck. Any other suggestions? I've been searching the Internet but don't see anything online regarding this issue other than what's posted here. Thanks for all of your input!
BTW, anyone know how the sensor down there works? It looks like it might send out a laser or some sort of infrared beam since the top half of the box is a dark clear plastic. Not sure what the bottom half of the box does, maybe sonar or electrical stuff to run the top part of the box?
