The most common problem with any electrical accessory is bad connections, either at the actuator that activates the trunk latch or the switch.
First check your fuse panel to be sure you haven't blown a fuse. The actuator itself can be eliminated simply by using a jumper wire to connect it to a known source of power to see if it operates as it should.
Then with a meter, check to see that you have power at the switch as well as the actuator. If you don't have power at the switch then the problem likely lies between it and the fuse panel. If there is power at the switch but none at the actuator start with the connections on the switch then the actuator itself. Remove each connection and clean both the male and female ends of each then reattach. Don't overlook the grounding connections too.
Electrical problems like this are sometimes very difficult to locate but taking your time and following the path of the current from the panel through every component is the only way to find where the problem lies.
