A/C compressor hose develops a leak.
Refrigerant and refrigerant oil leak out of the A/C system.
A/C system stops operating.
A/C compressor hose is replaced along with rear blower motor.
A/C system is evacuated to remove any air/moisture and recharged with refrigerant.
But no refrigerant oil is added to replace what was lost.
Everything works for a while until the compressor explodes due to the lack of oil.
Now the entire A/C system has to be disassemble to flush/replace components due to the exploding compressor.
