2006 X5 A/C Clutch Override?

I have INPA and scanned for codes. None were found.

INPA shows that the compressor is not active (visually as well).

The A/C compressor clutch is not engaging. I tried to force it to operate using INPA but it will not engage it.

Also, AUX fan is not on when A/C is in any setting (normal or MAX). I can not find how to test this in INPA - or force engage with INPA... However, I saw that you can unplug the A/C high pressure switch and it should make the AUX fan kick on. I did this and fan did not turn on...

I checked the low side pressure and it is way high (as you would expect with the clutch not engaging.

How can I force the clutch to engage so that I can get a reading and add R134 if necessary?

I suspect that the low R134 is keeping it from kicking on as INPA shows no other faults.

Thanks for your help!

If the static pressure within the ac system is "High" you don't need to add any refrigerant, and the low pressure is not the problem.
