Q: Variable displacement compressor not getting power

asked by on

How do I tell the variable displacement compressor is getting power, without an oscilloscope? I have checked resistance on the control wire and had 0 ohms. My scanner says that the a/c switch is on, and the duty cycle is at 95%. I have already replaced the compressor. The circuit is power side switched, and the PCM supply's the power.

My car has 100000 miles.
My car has an automatic transmission.
