Gauge is probably driven by computer and not the output from the temperature sensor and so gauge reading does not have a direct relationship with the actual engine temperature.

Generic obd2 scanner will read data/faults that can affect the exhaust emissions, which a computer driven gauge will not. Dealer/manufacturer level bi-directional software would be needed for in-depth inspections of all non-emission related systems.

Nowhere did you say you had checked the motor power supply - the typical heater motor circuit supplies the motor with power and provides a ground through the switch via the resistor for lower speeds and direct for high speed.

With late model fully computerised cars, switching duties are usually carried out by a black box at commands from the dashboard switch. Sometimes the circuits are unconventional which is why a circuit diagram is very desirable before troubleshooting.

you have to remove 8 screws on the back of the panel. The entire back where the lights are is one piece attached to the trunk lid, so you will be working over head. Remove the eights screws and pull the whole piece off. easy to do but takes a few. All back lights are accessable from there. If you need new bulbs or anything click here: Aliexpress Homepage and you can find anything for cheapest prices.
I hope this helped

They are inside the plastic back attached to the trunk lid. To remove it there are nuts recessed in the back of the lid that have to be removed. The wiring pretty much keeps the back from falling but you still want to be careful. You need deep recess sockets to get to the nuts.

I belive that year Buick has resistor on key shank. If you have a key to copy you can get replacement at Ace Hardware or other home improvement stores.
