I have a 1998 Mustang GT that the factory alarm triggers randomly and for no apparent reason. Just this morning it went off AGAIN and we had a neighbor in our front yard already complaining about it- this time. So I desperately need help and suggestions in what to do to turn this thing off or disable it. I had been leaving my car unlocked but that's
I'd like to be able to turn off the factory alarm but maintain the keyless remote, but that's a side note right now.
Can someone explain to me how I can turn off or disable the factory alarm?
Not sure if it has ever happened, but my 93LX had a problem years back that the dome light would turn on/off by itself. I don't know the alarm system on your 88GT, but if it's tied into the dome light circuit this may be a cause.
The fix was tor replace the drivers side door switch for the dome light circuit. It got wet/ruined once after going through a car wash. Crazy thing started dinging while driving down the road or just sitting in the garage. I don't remember all the details now, but the door switch was cheap and easy to replace. Best of all the dinging stopped.
Like I said, not sure if this is the case here, but it may be.
Thanks but I got it. When I posted, I had a full day of work ahead of me so I had no access to the car and was hoping to receive some ideas/input. When I got home I popped open the Owners Manual and started reading. I found that the Anti-theft is run by fuse in position 16 (Fuse is a 20) in my 1998 Mustang GT on the drivers side compartment of the car underneath the dash. I've taken that fuse completely out and now I get no theft light in my dash so I think it worked. By worked, I mean disabling the Anti-theft mechanism that is in effect, broke. Surprisingly, the keyless remote still works to lock and unlock the doors! (that was one of my biggest worries of disabling the Antitheft system but no more worries - well other than I need to get a new alarm system but I'm typically parked in a videotaped lot so I'll rely on that for now.
My neighbor mentioned that the random alarming might be because I am parked on an incline, but I have no time to test that theory since I am shy on sleep and my neighbors are completely pissed off at me.
Hope this helps out someone else and thanks for your support.
I think I can tell you what is wrong, and you can benefit from what cost me a shitload to have diagnosed. I had a 98 Cobra, same thing. I would walk away and it would go off or it would be parked in the garage and all of a sudden it was hollering.
I took it in and had it diagnosed. The found the sensor in the deck lid was bad and wanted !165 for the parts plus some awful amount to install it. I unplugged it and the thing never went off again.
That sensor is located where the latch is in the deck lid. Try unplugging yours. If that doesn't solve it, go on to the other sensors one at a time. I still have the service CD for that year model and can email you the schematics if you can give me a good address. At least I THINK I can, sometimes it's a PITA to get stuff out of it.

Thanks for the info, but I'm going to stick with the disabled alarm. I'd love to be able to troubleshoot, but my neighbors are pissed (and I don't want to push it any further) and I don't have a garage to test in (in case it does continue to go off randomly).
Sure do appreciate the help, hopefully others will be benefits from all the posts.
