If your Jeep Liberty's car alarm is malfunctioning, the first thing you should consider is an electrical problem. Car alarms are electrical devices that are sensitive by nature. Thus, even a small electrical problem can leave your alarm ineffective and your Jeep unprotected. Recognizing the most common signs of electrical car alarm problems will help you troubleshoot the situation and get your alarm working in proper order.
The Jeep Liberty's alarm, like other car alarms, has a siren-like sound. A couple problems could be to blame if you notice the sounds is becoming softer and more abrupt. The first is a wiring issue. The alarm runs off power coming from the car battery. Any damage to the car alarm's electrical wiring may cause insufficient power to feed into the alarm. There will be just enough for it to sound off but not enough to sound off properly. Damaged electrical wiring will have to be repaired by a specialist. It is important to note that a low battery can also cause the same symptoms as damaged electrical wiring. Turn on your car and see if your battery light illuminates on your dashboard. If so--or if the battery is completely dead--you can jump start the battery or install a new one.
One of the most common electrical problems is oversensitivity. This is when a incidental touch or small vibrations will set off the alarm. Not only is it annoying to constantly turn off your alarm, but it is also a nuisance to everyone in your neighborhood. As such, your car alarm will have to be readjusted to lower the sensitivity. This repair should be handled by a specialist.
With the proliferation of cell phones and GPS systems, it is increasingly likely that your alarm system will suffer electrical problems due to interference--the amount of waves in the confines of the Jeep Liberty's cabin can cause the alarm's electronic equipment to malfunction. Try turning off your cell phone, GPS device and any other hand held wireless device for several minutes and then try testing your alarm again. If your alarm starts working, the abundance of wireless devices is the likely problem. Make sure to shut off any devices you're not using while in the car to make sure the alarm is functioning properly.
