Thumbs down Not so quick or easy after all...

After conceding that the clutch was toast, I decided to check out the wellness on the compressor itself... Not good, it's completely seized. This is probably what took the clutch out of the game in the first place. So now, I'm fishing around looking for the best deal on a replacement compressor and receiver/dryer.

I can't wait to get started on replacing the lower control arm bushings next!

Also replace the condenser, and of course flush out the rest of the system.

How do I go about flushing out the rest of the system? Does pulling a vacuum on it achieve this?

No, pulling a vacuum is an independent step.

Flushing involves disconnecting every fitting in the system and forcing flushing fluid through to remove debris. You follow the fluid with lots and lots of compressed air to remove the solvent.

Parallel-flow condensers (as used in your car) are about impossible to flush, but not all that expensive.

Finally got my parts

The nice guy in the big brown truck finally dropped off my new compressor and receiver/drier today. After removing the old compressor, I decided to tear it apart just to see how bad it looked inside. Take a look and tell me if this looks like "Black Death" to you guys.

After several scheduling delays we finally got the system flushed-out, compressor and dryer replaced, pulled 28.5 in./lbs. of vacuum for about an hour, and finally recharged the system. With the current outside temperature @ 96*F, I have achieved a center vent temp of 52*F @ 1200rpm in the driveway. Is this up to par or should it be colder?

A 44 degree drop is pretty respectable. It will probably cool a bit better when in motion with good airflow across the condenser.

I realize the clutch is no longer the problem, but I think the impedance of a typical A/C clutch coil is around 3-5 ohms.
