The a/c compressor is switched on by the relay via a signal from both the climate control unit and the ECU. If you jumper the relay and the compressor will not come on, it could be the windings in the clutch magnet have burned out...hence the white smoke. I don't know off hand what the resistance of the clutch coil should be but probably next to nothing. Check with an ohm meter. good luck
