Question:

Car alarm goes off by itself, but only in the AM?

I realized this morning that it was my car's alarm that has been going off almost every morning (I live in an apartment complex). When I looked outside, no one was around the car when it went off. It only goes off in the morning too. Recently I was in a little accident where I tapped the car in front of me at an intersection-- there was a little damage to my front bumper/fender and hood.What can I do to fix this problem right away? Is there a way to disable the alarm till I can get the wiring checked? Why does the alarm only go off in the morning?car: Hyundai Elantra hatchback

Answer:

In many cases a misadjusted switch in the alarm system can cause the alarm to sound almost religiously at certain times or conditions. In this case it is possible that the temperature/moisture content of the air causes the switch in your hood to trip. ( I am assuming the hood switch because you mentioned you tapped a car with the front end of your vehicle ). If your vehicle is newer and equipped with a B-CAN system ( B-CAN is a type of communication system in the vehicle ) a shop, likely the dealership, can observe this data with a scan tool and tell you what the problem is. Keep in mind, there are other factors. Kids like to have fun. It is possible someone is messing with you. Or, the neighbors cat likes your car. But, only in the morning at a certain time. I am willing to bet that it has something to do with the hood switch ( if so equipped ) and you should see if a shop can help you out. Please, make sure to mention as much about the environmental conditions as possible. Time of day, temperature, humidity etc. It will help speed the diagnostic process and probably help save you some money.
you may have condensation crossing some bear wires. I would get it checked out so if some one dose do something to your car and the alarm goes off you know it is not a false alarm
