I'm having a problem with my new Viper alarm. It worked fine for a while and I put in its remote start capability and it worked great for a couple of weeks. Then it stopped arming all the sudden. It locks and unlocks and all the buttons work but the alarm never actually arms. As soon as I turn off the ignition the LED comes on and stays on. Also it seems to be screwing with one of my taillights or maybe the taillight is just mest up. Sometimes the taillight won't come on and when I do remote start it comes on after a minute or so, but that may be unrelated. I don't know why it stopped working all the sudden. Any ideas??
