HI Everyone,

I am having a problem with my reverse parking sensor. I have an early model 03 Expedition with the 2 sonar sensors on each side of the rear bumper and one radar sensor in the middle behind the rear bumper. I have already checked out the sonar sensors (they are fine). I would like to remove the radar sensor but can't figure out how to remove it. I dropped the spare tire so I can see better and the radar sensor seems to be installed in a block of foam that stretches the length of the bumper. I can see the plug end but no way for me to access how it actually housed. I can wiggle the foam a bit and the sensor seems to move with the foam so I assume it is mounted to the foam. Any ideas??? I would like to remove it to clean it and see if that helps my constant beeping problem when I am in reverse before springing for a new one ($460).

Thanks in advance for the help.
