Cadillac Repair: power door lock problem on 95 deville, fuse block, fuse panel


Question
I have a 95 deville 4.9 and when i hit the lock or unlock button on the remote the courtesy lights come on but the doors wont unlock or lock they also wont unlock when you hit the button on the inside from either the pass or driver door i get a clicking noise out of the black module located behind the rear seat whenever i hit any button on the remote or the lock buttons inside the car i checked the fuse block in the trunk and they all seem fine as do the ones under the hood i also accidentally set the alarm off before this started happening and the lights flashed but the horn didnt go off as usual then the power locks stopped working every thing else works fine and the car starts right up fine so im hesitant to run out and get a battery unless i need to also the courtesy light come on the way they should every time i hit the lock or unlock  button on the remote also the trunk does not open either from the remote since this started happening
