Air con clutch not engaging

[gtturbo87uk]

I have a 2017 transit custom 2.0. I have just had it regassed but now I notice that the clutch is not engaging on the pump. I have checked the relay and 2 of the fuses in the engine bay and they are all good. The gas is fully topped up too. What else could cause the clutch to not engage. Does it look like a new pump?

FOUND THIS - on how to test the clutch

Test the Electromagnetic Coil and Wiring inspection:
Ensure the electrical connector going to the compressor clutch is clean, securely plugged in, and that the wires are not corroded or frayed.

Multimeter test:
Disconnect the clutch coil and use a digital multimeter set to ohms 200 range to test its resistance. A functional coil typically reads between 2 and 5 ohms, Readings outside this range (or zero) indicate a bad coil.
Direct power test:
You can carefully apply 12 volts directly from the car battery to the clutch connector to see if you hear a "click". If it doesn't click, the coil is dead.

and how to use it in that range on multimeter

The 200 ohm setting on a multimeter is the lowest standard resistance range. It is used to measure very low-value resistors (0 to 200 ohms) and perform continuity tests on wires, fuses, and switches.How to use it:The Scale: The reading you see on the screen is the exact value in ohms . For example, a reading of 50.5 means 50.5 ohms.The Limits: If your component has a resistance over 200 ohms, the meter will display "OL" or "1" (meaning "Over Limit" or "Out of Range"). You will need to turn the dial to the next higher setting e.g., 2k ohms.Pro Tips for accurate readings:Test the leads first: Before testing any components, touch the red and black probes together. The 200-ohm range is precise enough to show your test leads' internal resistance—usually between 0.2 ohm and 0.5 ohm. If your leads show this when touching, your meter is working.Turn off the power: Never measure resistance in a live circuit. The multimeter sends its own tiny voltage through the probes; external power will damage the device.

all the best mark

does it come for a second or two when first swiched on ???

Does the clutch move at all when activated? If there’s any movement it’s most likely mechanical problem with the clutch (shimming or the splines). If absolutely nothing happens my guess would be electical problemo.

You should be able to by the clutch separately, no need for a whole pump if the splines are good.

Ended up pinching the fuse terminals under the bonnet together and it seems to have worked. Similar to when the electric fuel pump doesn’t work when the fuse terminal is loose
