remote door locks

I have a 2002 sc 2 3 door coupe. the trunk and door locks have blown the 10 amp fuse . when i replace it it will blow right away or maybe in a day or two. Most of the time when it blows the the fuse I have used the trunk remote. or just shut the trunk. I have checked the wires in the trunk , disconnected the wires in the trunk. to no avail. This has become a real pain because the interior light is on the same circut. any suggestion of where to look for a short.
