trunk won't open G6 convertable
did you find a fix? Mine is broken as well
the remotes are sometimes bad on those cars. its either the soldering that holds the battery clip or the buttons are worn out. Both very common but easy to fix. check out keylessfix.com for lots of advice on those gm remotes.
remove negative battery terminal connnection. wait 15 seconds, reattach. Trunk should open if you do not try to start car first. This is easier than jumping the relay
Check the trunk relay on the main fuse panel. Swap it with another one from another circuit just be sure to use one w/ the same number. I assume the button on the car isn't working. If true, fix that first before working on the fob. Chances are 2 things didn't fail at the same time.
I just chased down an identical problem. The wire to the release was broken under the plastic cover where the harness exits the deck lid into the trunk by the left hinge. If you can hear the relay click in the trunk fuse box when you press the release button but nothing happens, then you might want to check that.
