Does anybody know the location of the trunks proximity sensor

The small, rounds indents in the rear bumper? Or the actual module that controls the system?

The module or the antenna. My button on the trunk doesn't work unless I put the key fob into the trunk.

Re: Trunk Proximity Sensor Not Working - 05 STS

There is a antenna attached to the rear bumper, the steel one behind the plastic its almost dead center there is one plug that goes into it and there is a basic clip holding it in place it is about the size of a pack of gum. replace it and it will work they break. Think the part was $100. there are a few clips on the plastic bumper cover on the bottom pull out the plastic cover and you'll see the steel bumper underneith.

Hopefully this will help
