Or simply replace heater hoses with pipe plugs. No hoses going to the heater core = no heat.
Of course I live in tropical Queensland. No need for heat.

Its not safe to completely remove the operation of the heater core. There will be days when you need warm defrost / defogging.
However, you can remove the Vac Control Valve on the heater hose and throw it as far as you can. ****-poor design on a vehicle with so many vacuum accessories.
NAPA sells a manual shut-off valve in both 5/8" or 3/4", your choice for about $25. You can install that valve in place if the GM engineers not-so brilliant idea.
The valve can be opened in Spring or Fall and closed all Summer or cracked open a smidge. Fully adjustable.
And it does not look like it came off a washing machine at Home Depot.
