Went to my nearest Ford dealer on Friday and talked with one of their service writers. Explained my problem and asked how much it would be for parts and labor. Was told 2 hours of labor to remove and replace the A/C clutch assembly.
Was also told that the A/C system would need to be purged and recharged. I explained that I just had this done 3 weeks ago and it was my understanding that the A/C compressor clutch assembly could be replaced without
opening the lines (the service writer did not know whether or not that could be done).
The service writer had a parts guy look up the A/C clutch and gave me a price of $63.95. That didn't sound right to me --- I'd already looked up the A/C clutch assembly at www.rockauto.com
(thanks to a helpful member here!!) and knew that the part shouldn't be that
inexpensive at the dealer. I got the part number from the service writer and looked it up ---- it was just for the A/C clutch (not the complete A/C clutch assembly).
So... I still have more questions. Looking back through this thread, I can see where removing the A/C compressor clutch (just the clutch) might be a problem. But, what about removing/replacing the complete A/C compressor clutch assembly? The compressor seems to be working just fine, so I really don't want to buy another one if it isn't necessary!
