Dodge Intrepid electrical problem

I have a 96 Intrepid 3.5 ltr. I'm having a heck of a time figuring out this problem. When the car is started the air bag light is on, and the heater blower won't work, and the power windows won't work. If I turn the key back just a hair the airbag light goes off, and everything works. Occationally (but rarely) everything (the above) will shut off while driving it. I changed the ignition lock cylinder. This didn't work. The battery and charging systems are fine. I'm thinking these are all on the same circut, but every diagram I've looked at (auto zone) I can't find anything....help!

 

Lock cyl or ignition switch?????.Sounds like a switch problem to me.

 

lock cly, you think I should change the ingition switch?

 

yup!!!!!!!!!
