My A/C compressor has developed a new habit over the last couple of weeks. When I first start my 2014 Volt now, if the A/C is on (any setting), the compressor runs at very very high rpm for 15 to 20 seconds and then immediately drops to an imperceptible RPM and stays there. It does this same thing even when I have climate set to Eco, fan speed 1, and temp just below ambient. The first time it did this I actually thought the Engine had started for some reason. I can feel the compressor running vibration through the steering wheel and I can also hear the compressor running. By the way, when its at that high RPM if I quickly turn the A/C off, the compressor will turn off - no time delay. Prior to this new behavior I never heard or felt the A/C compressor regardless of the climate settings. Anyone else experienced this?
