Mine is a 96 with the same problem. Just started a couple of months ago and has gone bonkers the last two days. (When I park it with the alarm set, the alarm goes off runs for 45 seconds shuts off and cycles like this every couple of minutes.

I noticed the display indicating the passenger door is ajar when the lights go on and the doors lock/unlock. I'm hoping it is a dirty or bad door sensor.

I've seen several threads along this line, sounds like it is either this or a random short somewhere in the electrical system.

I'll let you know what works.
