Then noticed windows still have power after turning off key and opening door. So changed window relay. Still windows have power after shutting off. Changed ignition switch. Now ignition will not turn over& still have power to windows?

When you say you changed the ignition switch, the key tumbler, or the platic part that plugs into the harness?

Have you done a relearn on the pass-key?
GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it

You will have to scan for "B" codes with a scntool that is able to do this, most shops can scan B cods, and the dealer too. Try pulling the retained accessory power relay. It's on the top of the fuse box, and the breaker is on the bottom of the fuse box, after you remove it, see if the windows are now powered down.
