2008 Saturn Vue - lots of hazard lights, key turns, NOTHING.
Lot's of warning lights , check engine and all the others , You should have the vehicle checked for DTC'S - diagnostic trouble codes . Lost power codes probably ! Could be a number of thing's ,ignition switch , BCM - body control module just to name a couple . DTC'S will point in the right diagnostic direction . The electronic's on your vehicle Are complex to say the least .
The body control system consists of the body control module (BCM), communications, and various input and outputs. Some inputs, outputs and messages require other modules to interact with the BCM. The BCM also has discrete input and output terminals to control the vehicle body functions. The BCM is wired to the GMLAN High speed serial data buss and the GMLAN Low speed serial data buss and acts as a gateway between them. If the BCM does not communicate the vehicle will not start due to the inability of the engine/powertrain control module (ECM/PCM) and vehicle theft deterrent (VTD) control module to communicate without the BCM providing the gateway function.
Power Mode Master
This vehicles BCM functions as the power mode master (PMM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination the power mode that will be sent over the serial data circuits to the other modules that need this information, and so the PMM will activate relays and other direct outputs of the PMM as needed. Refer to Power Mode Description and Operation for a complete description of power mode functions.
This is something you should have checked out by a qualified repair shop .
