Hey guys,
I have a 97 GT mustang and this past week my alarm quit working. It used to beep once after about 20 seconds (automatic alarm setting) and now there is no beep. I can open the car door and no alarm will go off. It used to beep twice when I pressed the alarm lock button but now it beeps once. The alarm light is flashing differently too. It used to flash continuously and now it flashes twice with a half a second gap, then flashes twice again with a second gap...etc. Any ideas?

If its after market see what kind it is. Different places carry the different brands. Mine is Crimestopper and radioshack has them... Take it to them to see if they can figure it out..
