The security,or lock picture icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Newer cars come with a switches that delays their shut down of certain lights on the car. Sometime they allow you to get inside your home before the turn off but sometimes the switches malfunction and you light never turns off. I have had this happen on my 2006 vehicle several times in the past. Maybe these kind of switches one day will get a little better. Until then, you can ignore it or pay the big bucks and have a technitian repair it..

the control panel provides the signal to the relay which energizes the blower motor thru the switch and the resistor . signal first relay second all else third

It sounds like a mode door actuator. Pretty common.

Unhook the amp. Check the fuses and charge the battery.
