Just bought a Crossfire Coupe and the Alarm randomly goes off if the car is locked and the spoiler doesn’t deploy when reaching the speed it’s supposed to work, red light flashing on the interior switch and manual switch doesn’t work, can any one help?

 

Check fuse #16 in the fuse box under the hood on the driver's side. It doesn't have anything to do with the alarm going off but if it's missing or blown it will explain the spoiler not working and the red light blinking on the spoiler button.
