2000 Buick lesaber ,3.8Lt ,140,000mi
Hello, I have recently ran into a Problem that just bogels my mind. I drove my car all day mind you, went into a friends house and came back to the car (2000 Buick lesaber) and attempted to start it. It would not even turn over. No selections of the ignition switch would ingauge (key Pos 1,2,3). The lights illuminating the driver and Passenger door window and lock buttons are constantly on (have to unplug the battery) and the horn will stay ingauged if Pushed at all. The radio will turn itself all of the way u or down when battery is plug back in but, no power to it other than the tiny security light(on the head unit not dash). The power seats do move when battery is pluged in.I have no dash lights nothing other than the mentioned above.
WHAT I HAVE DONE:
Checked All grounds I know of.
Checked Battery
Checked fuses,fuse box ground studs
Removed ignition switch(Took it apart all contacts and wires are in pristine condition but what I observed was that the vehicle has the same problems with ignition switch removed so could that still be the problem?)
pass key 111 unit is installed factory but, the keys I have do not have chips in them, never have.(also security light it not blinking on dash)
Any and all suggestions and very welcome and thank all of you for taking your time to read and possibly help me out

Do you have an original working pass key to test this with? In that it can work without one it may (probably) was by-passed and that wiring work may be the issue now. Can only guess so far,

The Backlighting staying on on the switches is due to a unique software issue within the IPM.
GM issued a bulletin on this
Bulletin number 01-08-47-002
States to replace the Heater / A/C programmer Assm (also called the Instrument Panel Module)
Part number 12214171
Once replaced,the IPM will need to be reprogrammed so you'll have to take it to a qualified shop or the dealer for this repair.

Thank you for your reply I have never had a "passkey" with a chip in it but there is a pass key MOD and I do have both of the keys that came with the car none of them have chips
so checking the weiring to that would consist of checking for faults in the wires that run from it ?
