OK so after my last post was taken care of (thanks to all that helped out) I said I would be back because I own a Ford, Dam, sometimes it sucks to be right, here I am.
Problem, this has happened twice now: for absolutly no reason my alarm system goes off. This normally occurrs late at night, just late enough to **** off the nieghbors, my bad,
Does any one have any ideas, I really dont want to buy a Chevy.

1998 F150 4.6 XLT V8 4x4 crewcab.

PS when the CD player (6 disc changer) goes **** up, should I just go after market or try to fix the original one?

 

Is the alarm the factory one ( listed in the owners manual ) or an aftermarket one ?

 

SSCULLY
it is factory, if you recall you just solved my key fob issue, just before it was solved the alarm went off all by itself, and after I reprogrammed the fob and got it working the alarm went off by itself again, last night for no reason, other than she is a tempermental SOB. What might be the problem, if ever I run into you, I owe you a cold one, thats for sure!

 

Try WD-40'ing the door latches.

The Perimeter alarm should only go off if the doors are opened without using the fob or key.

The door ajar indicators seem to be the only thing to the RAP ( Remote Antitheft Personality ) module for the perimeter alarm.

 

My buddy's exploder's alarm did this every other night...come to find out a kid on a mopad was stealing gas out of it.

 

Thanks SScully, I will give it a try and advise you of my findings.
