You could have an electrical short also.Please let me know if the battery and alternator is not the problem and I will research possible electrical shorts and where they would be located.

I had the same problem on my 2002 Pontiac Grand Prix GT. I sent my radio out for repair of illumination. You can find online places that will provide shipping labels for sending the radio in and returning it back to you.

Most likely one of the blend door motors or wiring/ connectors. Check the plugs first. You will most likely need to remove the floor duct work to get to them.

Your ignition switch is bogus. High speed runs directly off the speed control but the lower speeds go thru the ignition switch. Do not know why but that is the way it is!!!!!!!!
Replace the ignition switch and you will be back in business.
Ignition Key Lock solenoid not working
The closed park position switch within the automatic transaxle supplies voltage to the steering electric park lock. The energized electric park lock pulls the mechanical lock in the ignition key cylinder away from the cylinder. The ignition key can then be turned to the LOCK position. The key can then be taken out of the cylinder.
I have 11.53v on the power side and ground side to battery has 11 ohms ? do a voltage drop test on the ground side not ohms . Do you know what voltage drop is ? Learn the right testing procedure , you could have broken wire strands inside the insulation , apply current an the circuit won't work correctly , but would show ok with ohm test's .

Low oil pressure light on at idle
first check the wire going to the sensor, give it a good clean on the conditions. if this does not sort the problem it could be because of the oil change, muck in the oil could of gotten into the sensor, you maybe able to clean it out but you may need to replace it. when an oil change is done they would put a cleaning agent in with the oil, this loosens any burnt oil off the engine, this burnt parts can stay in the engine and float around and even block the pressure sensor.

The day time running lights module , ambient light sensor , would be a good guess but that's all it would be .Do you know what these are ? Really don't think there is a short in the multifunction switch . Maybe it's time to take to a qualified repair shop , dealer ! Cadillac or Buick .
Daytime Running Lamps (DRL)
The Daytime Running Lamps (DRL) control module is designed to automatically operate the exterior lights depending on the outside light conditions.
The DRL control module operates in 2 modes:
• The day mode
In the day mode, the DRL control module turns ON the low beam headlamps at a reduced intensity when the DRL ambient light sensor detects daylight under the following conditions:
- The ignition switch is in the RUN position.
- The headlamps are OFF.
- The park brake is OFF.
• The low light mode
In the low light mode, the DRL ambient light sensor detects darkness, turning ON the low beam headlamps to full intensity through CKT 10.
Additionally, the DRL ambient light sensor turns ON the following lamps through CKT 9:
- The park lamps
- The side marker lamps
- The license lamps
- The tail lamps
