Question about 1998 Dodge Caravan
Headlights went out when trying to fix the horn then alarm goes off by itself
Door locks cycle as you are driving? if this is the case a common cause is the switch going bad that shows the sliding door is closed.

SOURCE: Alarm system
you might want to get a new key from dealer, just make sure you turn key all the way when you unlock. if this does it again, just start the vehicle for a quick fix.

try disconnecting the battery for 5 minutes and then reconnecting it. Not likely, but easy to do. Also look for a burned 'fusible link' in the underhood fuse box or a burned large capacity 'fuse'. TH eheadlights and power seats are high current loads. The door lock problem is likely a door switch not connecting--and will not allow the doors to power lock when the computer thinks a door is open.
Also have Autozone, HiLo, O'Reilly's, and other parts stores test the battery and charging system (It is free). A weak battery or charging system causes low voltage, and the electronics do not like low voltage.
Also ask them to 'pull the codes' for the engine computer and transmission computer. also free. Sometimes things happen that do not turn on th 'check engine' lights, but still point to the problems. The entire 'Intrepid' line and twins have integrated computer systems with 'bugs' in them. A good friend gave up trying to get his fixed--and just quit using the alarm system--the trunk would open after about 1 hour!!. Finally the transmission and its computer started acting up and would start jumping back and forth gears after a few minutes in stop and go traffic. After 3 tear-down , inspect, reassemble efforts by a good transmission shop, they gave up, replaced the transmission at no cost, and it also did the same thing--confirmaing the problem was in the wiring/computer system. He sold the car.

On internet there is a manule, disarm the Anti-Theft system. Check door and trunk switches re-engage system.

You have a short in your Electrical system where the alarm connects to your power assist system or a short in your alarm. Pull the fuse for the alarm and if the problem stops it is the alarm if it continues you will need to trace the connections and make sure they are secure and protected by taping them up.
