Hi there. Typically when the vehicle is running, power to accessories and ancillary components like the AC system will be supplied by the alternator. This means that when you have inconsistent power problems like you’ve described, it is usually due to a bad alternator or other charging system component. You might want to have a professional mechanic come to your location to complete an electrical problems inspection, to determine precisely what is causing your problem.
