I have a 2004 2500 Sierra with a factory alarm. I live in the San DIego Area. The alarm has been going off about every other night between 12:30am and 2:30 am. I watched several nights just to see if someone was tampering with the truck but nothing like that. It's parked in the driveway and just goes off. Anyone have any similar experiences with alarms going off for no apparant reason? It's not too cold out, the batteries are fully charged, and there's no unusual weather or earthquakes going on? Driving me crazy. Don't want to disable the alarm and be vulnerable to fuel thieves! Anyone got any ideas?

I used to be able to replace it and the circuit would work for several weeks or even longer. Now it lasts several minutes and does not seem to blow for any reason. 1. the compass and thermometer in the rear view mirror. 2. the auto dimming function. 3. All chimes. 4. Airbags. |

| Does anyone know of a way to upgrade or convert the computer in a 01 Silverado so that half of the injectors are not used while on the highway. | |

Replying to: jfred09 (Jul 12, 2008 12:21 am) Personally, I'd check the power connections first. That is where the guy is getting the power for the lights, etc and go from there. Could be he has a few of them crossed or all connected to the same place. Watch for splices as the factory doesn't do that only diy installers. |

Replying to: sdlerner (May 30, 2008 6:55 pm) Did you get any aftermarket add-ons or did you get another alarm to supplement the factory? If you did, most of them don't work well with GM vehicles. I went and had a Viper put in instead of the Factory. Much better protection. |
