There isn't a fuse, the clutch is powered directly from the control module (it's not a high current circuit) check for an output on pin 2 of the black three-pin plug on the back of the climate control module. When you say it's engaging & disengaging, what do you mean? does the system pressure change and the Evap. temperature drop? |

When I press the AC button, the clutch engages and disengages. And I can hear the compressor too. Though haven't been able to see it from above.

It sounds like the climate control & compressor clutch is working fine, possibly the climate control module isn't measuring / reporting the current draw or the diagnostic software isn't polling it correctly.

My specific concern is the zero current drawn for compressor.

So other that the reported current draw, the aircon is working fine? If so, it's either the climate control module not reporting the current draw, or your diagnostics not polling the climate control module for the data correctly.
