All the funny noises under the hood are gone and the car acts like a Cadillac once again.
In that case you should have replaced the condenser as well and flushed all the lines.

Re: Air conditioning compressor clutch bearing

Ranger is correct - that's exactly what I was told had to be done to ensure the best and most durable results. Maybe you should look into having the system evacuated again and pull the orifice tube and see if it has caught any more trash; or ideally, you should evacuate and flush the system, replace the condenser, and also install another new accumulator. I was told that the reason to replace the condenser is that the tubes are so small you can never be sure they are all clear after flushing.

Re: Air conditioning compressor clutch bearing

I believe the reason for changing the condenser is that they are no longer serpentine, which would ensure a good flush. They are now a ladder type so they are almost impossible to guarantee a good flush.

I think you're right, based on what I have read about the design, but that wasn't was I was told - I was told it is because the tubes are so small. But again, I think you're right - the design is the real reason.
