2000 GMC Jimmy car vibrates

Question type: Maintenance & Repair
When I am at a stop light the car makes a weird vibration
sound. I pulled the glove compartment out and heard the
vibration sound coming from this black box. A person I
knew said it is probably nothing to worry about.

So to add on to this my thought is it could be the blend door actuator gone bad and its making that black box vibrate?
The temperature door actuator is a more likely suspect. It's electricity operated, while the mode door is vacuum operated. If you're also hearing a clicking sound, that too points to the temperature door actuator. Hope that helps! Jim
