Ignition Problem
 

Need assistance from all you Chevy veterans. Wifes car accessories sometimes dont come on when she starts car. Sometimes they come on later randomly while driving car. If she wiggles the key or restarts her car eventually her wipers and radio eventually start to work. Also sometimes her starter stays engaged after the engine is started. Need to figure out what parts I need, and what programming may need to be done. 2004 Malibu Classic 2.2L 80,XXX miles.
Also any actual part #s would sure be appreciated.
