Car Alarm Keeps Going Off--checked Hood Switches

[taradenise22]

I just drove my 2005 Hyundai Elantra from California to Pennsylvania without a problem. Once I arrived in Pennsylvania I took my car in for a state inspection. About 24 hours later my car alarm kept repeatedly going off. Eventually it stopped. When I tried to start the car it was dead. About 3 days later I had the car jumped. It ran fine. About 3 days later the car alarm randomly went off. I turned the alarm off and ran the car for 30 minutes and it was fine. About 24 hours later the car alarm randomly went off again. I turned it off and started the car. It ran fine. I checked the hood switches which was suggested in another post and they appear to be okay. There also doesn't appear to be any water around the battery.

What else could be causing this problem? Do you think the mechanic who performed the inspection could have hit something--my mother has had problems with them causing new problems after fixing old ones? Could it be the alternator? Could drastic temperature changes cause the problem--it does seem to happen when it goes from bitter cold to warmer, or is that just a coincedence?

Thanks!

Have you checked to make sure all of the doors are closed? This may seem obvious but this happened to my dad and it has happened to others.

i had the same problem on my elantra ,i fixed my problem as follows ,when you open the drivers door there was a little black push in switch on the door column which when the door is closed pushes in ,on mine it wasnt pushing right in with door closed so my alarm kept going off ,on the inside door lip which presses against switch i stuck a piece of rubber and hey presto when the door closes now it pushes the switch right in and no more alarms going off

Bob001. Feel free to keep your question here, but you also may want to present the question in the Tuscon subforum so as to get responses from other Tuscon drivers.
