If you unplug the pressostat switch and jump the 2 leads, with the engine running, the clutch should activate.

The clutch needs 13V to engage. If you give it 14V directly from the battery, it will also engage and allow for a larger clutch gap.

There is an inline thermostat on the wires going to the compressor, which cut power when too hot. Because of the 'white smoke', check those wires running around the bottom of the compressor.

If you have access to a pick&pull, get a pressostat and a relay. Same items in the 850s. An 850 ECC unit will not work in your car.
