Yep, this is common when one of the blend door actuators for the HVAC system has gone out. Here are the locations of each, the idea is to put your hand on them while the noise is being generated so you can find which one is bad and needs replacement. Once you have found the actuator in question here is how you can reprogram the unit once the new one is installed. This generic guide can help you see what you are in for when doing the job. Check out the images below. Also, I have included the actuator recalibrations instructions as well.
