intermittent buzzing zapping noise coming from dash board center to drivers side extremely annoying
Peter, get that car to mechanic ASAP as you do not want it to catch fire and/or get immobilized at the least convenient moment
Is it possibly coming from the stereo system speakers?
Noisy HVAC actuator servo motor, could be a lot of labor involved, probably not an urgent repair. When the noise occurs switch from hot to cold, fresh air to recirculate, floor to defrost, see if any of these things stop the noise.
