What to do if my auto A/C Compressor fails ?

Technically the compressor can be rebuilt ,it is recommended to replace the entire compressor. If there was a major internal compressor failure the entire system must be inspected for debris(metal from internal compressor components).After an internal compressor failure, it is  recommended to replace the A/C condenser(Specially if it is a modern Parallel Flow type) and the drier, to avoid contamination of the brand new air conditioning compressor. Also, the system should be flushed to avoid contamination.
