'99 GC...need to fix alarm, (or disable)

I have a '99 Grand Caravan (3.8) with 75k miles...

I cannot figure out what is going on with the alarm system. I lock the door (with either the transmitter or the door lock), and after a while the thing starts blarring like someone is trying to break-in. It will do this at varying intervals after being locked...shortest was about 1 min longest has been a couple hours.

I have no idea how this started and when it did this for the first time, I didn't even know it came with an alarm. Been going for about 3-months now and my wife is afraid to lock the van.

I did hit a deer in June on the left-front and had that fixed. I noticed the Relay Center is up in that area, but I didn't notice any damage to it, but I figure there must be some connection to what's going on.

I would just as soon disable the thing as pay money to fix it, but we'll see.

Thanks for any help,

Is this the OEM alarm? Does it honk the horn or a siren? My guess is that you have a problem with a door pin switch.

OEM = Original Equipment???

If so, yes. This alarm came with the vehicle. The lights flash and horn sounds.

Thanks,
