All temperature readings are good, air conditioning works properly, and the cooling system has been flushed.

Original thermostat is still in, car is at peak operating temp when turned on. Havent checked the heater core or thermostat.

I had the same issue (not blend door) and it turned out to be air lock in the heater core. I changed the thermostat and then took the top hose loose that comes out of the firewall at the 3 way connection. Take it loose so only the hose coming from the heater core is off. Turn the engine over and wait until antifreeze comes out of this hose. This will be messy so make sure you have a big catch pan. Once this is done, reattach the hose and add some coolant to the tank. I would run the car with the cap off for 30 minutes or so to burp the remaining air from the system. Top off antifreeze and you should have heat.

It's really user friendly and I'm just so happy that I found out about it. Here's what I've been doing.............https://bit.ly/2qPkxOO

your air damper or diverter may not be working.this is basically a mechanism that opens a flap by your heater core to control the amount of hot air that comes out.There is a rod that this flapper pivots on and if this rod is broken or the motor that operates it is not working you will either have heat all the time or no heat at all depending on which position it broke at.I know because my torrent has the same problem.To fix my problem they have to remove the dashboard to access the heater core which amounts to major $$$. I hope your problem is an easier fix. good luck

Hello first of all
Your blend door motor / acuator is bad its basiclly a door that opens and closes when you flip your
heat to ac dial to either allow the hot air through the vents or cold air.
That being said on some suv and cars and trucks you can replace the motor that controlls this blend door can be changed without removing the dash and some you haveto remove the dash.
The blend door is located right by the heater core in the dash but sometimes the motor that controlls the door blend door is accsesable without dash removal and sometimes it is. I posted a picture below of what part is bad i hope it helps you.
If it helps please leave me 4 thumbs up thanks

It sounds like your blower motor has died. This is pretty common for older Bonnevilles. I have a 2005 Bonny and replaced mine last year after 75,000 miles.
But first check your cabin filter. You may or may not have one. If you do, and it gets plugged up, you will get very low air flow. I had an Impala that get plugged with a mouse nest. If it's like mine, open the hood, and above the firewall on the passenger side and below the passenger wiper, is a cover labeled "air filtration system". It has a couple clips, remove it and look inside. It will be very obvious if you have a cabin filter. (I didn't have one) If there is no filter, you should be able to look down in the hole and see the white fan blades about 10-12 inches down. They should be spinning if the blower is on.
Not spinning? Next you should check the fuses. The fuses are probably under the back seat, but check your owner's manual.
If fuse looks OK. It's probably the blower fan.
The fan is under the dash on the passenger side... just about where the passengers left toe would be.
Remove the panel under the dash; probably a couple 7mm screws.
Unplug the fan. The center wire should have 12+volts.
Remove the rubber vent hose... kinda on the back of the motor.
Remove 3 screws. Probably 7mm. And the blower should come out.
I know my blower is different than yours, but they pretty much look the same.

Even if there were no hydrocarbons detected I am almost positive you have a bad head gasket.Usually the back head on the number one cylinder.Almost all the ones I have done with this exact problem has been the rear head and the number 1 cylinder.Hair line crack between the cylinder and water jacket.I always replace both head gaskets.Hope this helps.Good luck.
