Rain Sensor Inop - can someone measure the cutout?
Bought my car with an aftermarket windshield. The rain sensor didn't work from day one when I got it. Reading around people thought it was because of the aftermarket glass and prism that the sensor doesn't work. So I obtained a rain sensor with prism from a BMW windshield and glued it to my glass with clear silicone.
I've tried about four different rain sensors and tried gluing different prisms using different clear glues and finally ga e up after using the permatex clear glue from the e46fanatics website post that seemed to work for so many people.
Nothing works. In INPA, all rain sensors have the "can't initialize"error. Also all of the values are 255 for the measurement and 0 for the output. I'm at a loss unless it is the refractory index of the windshield that is screwing things up or the cut out for the rain sensor is too small. On this windshield, the cutout seems very small height-wise because I can barely fit and align the rain sensor on there and get both ends of the optical sensor input/output nubs within the cutout.
Could anyone with a BMW windshield with working rain sensor measure the width and height of the cutout in that black stuff below the rearview mirror? Thanks
