It's real common for the clutch coil to fail on those, and can be replaced without replacing the entire clutch.
But,
If the compressor locked up, or made noise, it's similar to an engine that grenades. That debris has to be removed by flushing the parts not being replaced. You can't flush the evaporator without removing the x valve, and it should be replaced regardless. The condenser can't be flushed and should be replaced as well. It also has the drier built into the side of it.
Even if it didn't "blow up", and was diagnosed as leaking, it's been running on the same oil for 9 years. That's reason enough to flush it, especially since it only has a few ounces in the entire system....and the only way to get the proper amount of oil charge. Not enough=destroyed compressor. Too much=loss of cooling.
Not sure how you would drain the freon without a machine. :Rolls eyes
You'll still need a vacuum pump to charge it.
The smaller the system the more important it is to do it properly.
