Your problem is being caused by the GM Passlock security system. It basically monitors your ignition keyswitch to determine if it has been turned without the proper key inserted. However, this system can begin to operate erratically as the vehicle ages (and the keylock cylinder has been turned numerous times). The owner's manual recommends calling GM roadside assistance for immediate help, or taking the vehicle to a GM dealer for repair. This system can be (and must be) overriden when installing a "remote start" system on your car. I know folks who have purchased the override module just for the purpose of removing the security feature due to its erratic operation.

+++++

read up on the system and check all the basics... everyone should have a manual for their vehicle, and the local library should have a SHOP manual available in the reference section--make copies of the right info and read up..you'll be a pro in no time ...good luck:)

The security light will blink when either door, hatch, or hood is opened and will continue blinking until it is closed. Check all 4 switches for proper operation. If the bad switch is disconnected it should turn off the light. If the security light is on constantly instead of blinking that is to let you know that the alarm system is activated and should turn off after a few minutes.
