Hello. Yes, your Chevrolet's security system will 'shut-down' the ignition system; causing your truck to start but stop instantly. The truck 'thinks' it is being 'stolen' and will 'enable' it's security system to 'hamper' stealing it. Good luck and keep me informed; if you want to.

The problem will usually be because the air diverter door actuator on the HVAC box under the dash has failed, is stuck or is not getting the required signal from your HVAC control system.

To replace the console is fairly easy BUT it is time consuming. Assume this is going to take you all day to do. Remove both front seats. They will possibly be Torx head bolts so you will need a matching socket. Don't use a standard socket as it will chew the bolt head. Disconnect the wiring under the seat for power or heat features. Once the seats are out the middle section should lift free. The dash section is bolted in place to the underside of the dash. Removal is centre first, dash second. Refitting is the other way round.
