If you can get in there and get it out without too much trouble, you can switch it with the temperature actuator which is on the bottom of the HVAC case and easily accessible. Both actuators should be the same part number. Just don't plug the actuators in until they are bolted to the HVAC doors as the actuators may do a self test. If there's nothing there to stop them they'll over-travel and stop working and (according to GM) will be damaged. But in reality you'll just have to pop them apart and reset the gear/shaft to the middle position.
perfect. thanks dustin! much appreciated :hug:
