You can also try shorting (putting a wire accross) the clutch cycling switch while the A?C button is pushed at idle. The clutch will manually cycle if you do this for testing. If your switch and clutch are both fine, your high side pressure is out of range and your clutch is not engaging as a safety precaution.


Kicked it on with the jumper which caused the gauge to show empty. Filled it while the jumper was on but the clutch will still not kick on without the jumper attached.
