Possible A/C clutch issue

[Tom]

Sure sounds like the clutch just isn't engaging, for whatever reason. I wouldn't mess around with trying to fix the compressor you have if it's been sitting around for years, personally. It lived a good life. Replacements from Denso are around US$400, and easy to find at least here in the US. Ester 100 oil a safe choice if you are converting to r134a, though I'd still flush the system. Be sure to change all o-rings, the receiver drier, and even the rubber hoses to the extent feasible. I could believe that the base compressor is the same as the 928, just with a different manifold and belt pully. In fact, when I replaced mine, I had to swap over the manifold from my original compressor, suggesting the manifolds are Porsche parts and not Denso parts, maybe....

Here's a link to our handy-dandy Carpokes 944 a/c compressor replacement guide.

Thanks guys. I am pretty sure back in 2003 when I previously had the AC re gassed the guy converted it to R134a. I can't remember whether he changed the seals, drier etc at the time. Think I'll just book it back in with the mechanic.

Quick update. I connected a lead from the starter motor to the wire pictured at the red arrow on a previous post. The cooling fan started, but crickets from the A/C clutch.

If it walks like a duck, swims like a duck, and quacks like a duck, then the clutch is toast.

Quick update. A new A/C compressor was going to cost me $1800 AUD. Found a new one on Aliexpress for $300 AUD delivered to Australia (approx $185 USD). Ordered on 8/Jan and arrived 15/Jan. Had it fitted today and appears to be working perfectly.
Thanks again Tom and dr bob.

Ali Express you say. Looks good. Who knew! Glad you got it sorted and cooling your car again!

Great find on that compressor! Report back after some time with it and help me decide if I need a spare for the shelf.

I wonder if Our Hero's new tariff increase would apply on a onesy purchase like this. Still a great deal. Thanks!
