incredible update...car shop called and told me to come get car..they had ran all diagnostics and there was nothing they could do...all major systems had shut down computers dead, modules not responding and I was looking at thousands of dollars of repairs above their capabilities...I was in despair and about to cry...started shopping for a new cts.
Last couple of days I have been pouring over wire diagrams on the entire car and trying to find a common denominator besides the ignition switch i already replaced. Three things constantly came up.
2. Interface plug in
3. Ignition 1 relay
Car shop mentioned that the underhood fuse board was half dead problem needed to be traced down to exactly what module shorted everything out...it made sense but didnt.
I kept thinking about what jwfirebird said about ign 3 relay and had nothing to loose so when i got home i started to swap relays...here comes the incredible part....swaped out ign 1 relay with high beams relay(one i know worked and could do without temporary)....and voila!!!!! everything came back up and works like new.
thank you everyone for the ideas and determination not to sit on my butt and scratch my head...only bad part is I did see a nice cts-v I coulda been in if i wanted to stop paying my internet bill
