Car Alarms: 1996 Ford E-150 Alarm, dash area, flip switch

Question
I have a 1996 Ford E-150 Van. The alarm started going off when it rained even if the doors weren't locked.  It has done it off and on for 5 years! The only way I can get it to stop is to unhook the battery! NOW it goes off whenever I stop the engine.  It won't go off if I keep clicking the unlock button on the key chain.  I do this until I can unhook the battery! HELP
It is driving me and the neighbors crazy!  

Answer
Ok, try this.
Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, press and hold in the valet/overide
button, found under the dash area,
until the installed LED (the blinking light)
in your dash area comes on solid.
(Your valet switch might be the toggle (on/off) type.
in this case, key on, flip switch in oposite direction,
key off.)

This should be valet. This overides
the starter kill relay in the alarm harness,
and returns the car back to disarmed mode.

The only thing that will work now on your system,
is the keyless entry if installed.

Just Repeat these steps to rearm your system.

That should do it.
If you want to remove it at this point,
take it to your neighborhood installer
for this, or buy the wiring chart for
the vehicle, and reverse engineer it wire
by wire, until it's safely removed.

Let me know what happens.
