2005 Cadillac Escalade DRL sensor

Interior problem
2005 Cadillac Escalade V8 All Wheel Drive Automatic 73000. Miles

I have a 2005 Cadillac Escalade and was cleaning the dash and the amber cover popped off the sensor and of course fell into the defrost vents. It must of been broken when the changed my windshield. I bought a new sensor at the dealer thinking I could just take the amber cover off and put on mine but no, its glued on. Now I have to change the whold damn thing and can not figure how to get to it without major surgery. Whould you know of any way to fix this? Thanks
