Very informative thread, wish I'd read it a month ago before I changed my compressor. Would probably have been much cheaper. Kudos to the experts for sharing their knowledge.

Ok, closing my story.. eBay coil works good, AC blows cold, everything put together and works just fine.

Hopefully it will help somebody avoid compressor replacement

In a rush to get a/c working again due to hi 80's weather around here, so i bought fsu from dealer today. After work, started car and blower was working cold air and i'm looking at new fsu,,, what to do with it ? Is it possibel fsu may fail again ?

Glad to see it's working for you, and I will keep this in mind if mine ever craps out!

I forgot to mention that I did install diode. I used one of those I had for car security installs. They pretty generic diodes. The reason I decided on using diode is because coil itself is somewhat capacitor. When power goes off - coil releases current back into circuit and could damage electronics.

Spent 5 minutes with soldering iron. Installed diode and transferred connector. I didn't take picture of finished product but if you will have coil out you will understand what to do. Make sure install diode in proper direction

I think my A/C Compressor clutch is nearing the end of its life. Occasionally I'll notice a very slight vibration. I can't actually feel it, but I can see it in the reflection in my rear-view mirror when at a stop light. I've noticed that if I turn on the A/C, vibration goes away. Turn A/C off, and vibration comes back most of the time.

Anybody have any thoughts?

Yes, I think AC doesn't have to do anything with it. When you turn on AC - ECU increases RPM's to deal with added load.

Looks like you have engine vibration on lower rpm's. Could be many things.

The air conditioner will not activate unless the aux fan is functioning. First try the 50A fuse relative to the aux fan to see if it's blown. 100,000 miles seems to be the design life of the fan.

If the fuse isn't the issue, then try bypassing the relay and power the aux fan directly from the + terminal of the battery located in the hood. If the fan doesn't run then obvious that is the problem.
