Remove the cap from the surge tank. Set the heater control temp to max (A/C in any mode EXCEPT max). Start the engine and idle until lower radiator to pump hose is hot. Allow the engine to cool to ambient, and then check/fill the surge tank and replace cap.

The drain valve is at the bottom of the radiator (as usual) - have fun getting to it!

There isn't one !
Filling Procedure
Notice: Do not add cold water to the cooling system with the engine at or above operating temperature. Adding cold water causes rapid cooling, resulting in possible engine damage.
NOTICE: When adding coolant, it is important that you use GM Goodwrench DEX-COOL® or HAVOLINE® DEX-COOL® coolant. If Coolant other than DEX-COOL® or HAVOLINE® DEX-COOL® is added to the system the engine coolant will require change sooner; at 50 000 km (30,000 mi) or 24 months.
Notice: Do not use a solution stronger than 70 percent antifreeze. Pure antifreeze can freeze at -22°C (-8°F).
Important: This engine is not equipped with block drains, 2.5 L (2 qt) of residual coolant remains in the engine block.
Refill the cooling system. In order to ensure sufficient engine cooling, freezing and corrosion protection, maintain the protection level at -37°C (-34°F) or lower.
Start the engine.
Place the heater and A/C control in any A/C mode except Max and the temperature in the highest setting.
Allow the engine to continue idling until the lower radiator to water pump hose is hot.
Turn OFF the engine.
Allow the engine to cool to outside temperature. Ensure the coolant level in the surge tank is at the proper level (1).

A verity of thing's could cause shifting problems , besides TPS ! You best bet would be to have it hooked up to a scan tool that can read sensor data parameters . All engine an transmission sensors work off vehicle voltage or a steady reference voltage from the PCM /TCM . Usually 5 volts ! but can be 8 volts on some vehicles . A veteran tech can tell if a parameter is out of limits one way or another . Guessing never works out !

Power Door Lock Operation
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.
Power Door Lock Components
The power door lock system consists of the following components:
Driver door lock switch

Passenger front door lock switch

LH rear door lock switch

RH rear door lock switch

I would start by having your battery and alternator checked. You can have that done for free here. In Store Services In Our Stores AutoZone com They can also charge your battery if needed. They can replace your battery for you if that is the problem. You may need a mechanic's services if the alternator is bad. They can recommend a reputable shop if needed.

Are there any hvac trouble codes ? Did you check voltage and ground for front blower motor, with controls turned on? I believe the purple wire is voltage and black wire is ground. If good voltage and ground with no blower action, suspect the blower motor.
With auto hvac didn't see relay, saw blower motor control processor, at control processor, did you check voltage and ground?
As far as replacing the blower motor control processor, that appears to be a very involved procedure. I can't lead you step by step to remove and replace.

Sounds like a faulty regulator rectifier on the alternator borrow a compatible alternator to test the charging system
It usually is cheaper to replace the whole alternator than have them repaired
