TTA Trunk Lath

My trunk latch mechanism seem to not be working anymore (can't close it). There have been times it has been stuck in the wrong position and i've been able to reset it by sticking a screwdriver in it and hitting the switch. That does not seem to work anymore and the pull-down motor is running all the time now. I have to disconnect the battery to keep it from possibly burning out the motor. Anyone have an idea of what could be wrong?
