its different every time. sometimes just a little while and sometimes for hours.
Chevy Mechanic: ZZDaryl, Chevy Technician replied 2 years ago
The only way to determine the problem is to do some electrical testing, start at the compressor and check for power and ground when the compressor is not working and if there is power and ground just keep working away until you find the component that is not allowing the power or ground to get to the compressor. If you need more help with that let me know and I can try to guide you.
