Hi aguet6825,
There should be 2 fans and both of them should be working when the AC compressor is engaged.
If the fan vibrates, most probably the motor is bad.
Are you sure the fan works when the AC is not cold? It should be the other way round.
What was the engine idling speed when fans work and stops?
