Do you mean that the orange wire is unplugged from ignition switch and the orange wire STILL has 12V?
Or you mean that the orange wire HAS 12V when plugged in the ignition switch at the off/lock position?
If the latter; your problem is a shorted ignition switch {the 'Run" position connectors are frozen}. | quote | rear emblem or "pontiac" lights seem to be on constantly even with the car off and no key in the ignition

This because the shorted ignition switch / the orange wire feeds Fan E Fuse at the 'Run' position and powers the 'Pontiac' bulbs
| quote | the hvac control head suffers from a similar issue in that i can turn the blower on and control all fan speeds with the key off as well. |
|
Same issue - 12v power is from the switch 'Run' position too / the orange wire feeds HTR A/C Fuse to the blower switch
| quote | Finally once the radiator fan is activated it will continue to run until the engine temp is cooled down even with the key off. |

This is normal
