Here's what I got from that:

The plastic holder/outter sensor for the rain sensor got damaged during the installation of his new windshield. Now it wont work properly in auto or regualr mode due to a problem with the way the sensor is on the windshield; so he took out the sensor, but his auto function for the headlights won't work. Now he's thinking of using epoxy or some kind of glue to get the sensor back on there properly. Have any of you had similar experiences?
