I had Alarm problems,, spent around $500 on it to later find that I had wires breaking in the harness between the door and the body. I also have a bad ac evaporator, so I started to tear out the dash and found that under the panel just right of the vehicle info display is a module that I'm sure controls the anti-theft. All I know is that I pulled it out and since there hasn't been anything to hint that the anti theft is doing anything. A check is to disconnect your battery for a bit. When you replace the cables the alarm will go off if the system still works. If no alarm,, it's probably dead. Good luck.
