MDK - No idea. I would call the dealer, give them your VIN, get a price and part number.

I checked FCPEuro for a 2004 S60 R (type) and it provided an A/C compressor and made no reference to "rear head switch".

Thanks superherman... I did go to the dealership today about 4 o'clock est and the parts guy said 762$ for a compressor.. without the clutch! Do all Volvo dealerships operate the same.?Here in Cincinnati I have to go to the parts counter .. get that quote for parts and then go to the service desk and get a labor quote... I suppose if I was some prominent sovereign citizen with 2 saddle bags of overflowing gold I could expect to be treated fairly... Hmm

MDK - I fully understand. Every time I go to the Volvo or BMW dealership I feel greased. Lately they have been marking up parts over MSRP.

Hopefully you got a part number on your quote - if so take your business elsewhere.

No clutch allows them to make more money on the part and on the labor.

You can always pull the part number off the A/C in your car and do some searching. The part at FCP was around $350, and the picture shows it has the clutch.

You will find the OEM sticker with manufacturer and their model number on your compressor, duplicate in kind on the webs for about 1/2 that price. It might refer to the thermal inline switch on the clutch wire.

Thanks guys.. I really appreciate you all. You all have been a great help to me the few years I've been on this site. I guess I'll take my time and start taking it apart as the S60 is my backup

I can't recall seeing a rear head switch on a P2. It was used on P80 through 98. It was a temp switch that opened compressor clutch circuit if compressor got hot. It used to switch lots of compressors off on hot days when the refrigerant was low as little as 2 oz but there was NO issue with cooling in the car.
Valeo, the OEM compressor, is $364 + shipping at RockAuto with clutch.
P2 compressor failures are rare, what is wrong with it?

Hey J 57... That's good Intel you gave. So, on mine, it's the clutch itself. I have a bad whining noise at idle. Took the belt off and grabbed the clutch bearing and .. well.. it's wobbly. I asked the guys at Volvo and said I could just replace the clutch itself but they said with 158,000 on the odometer I should probably just replace the whole unit. I hit the brakes when they gave me a quote for the parts and the ABS kicked in when I got the quote for the labor. I'm going to the scrapyard... Again.

Pull the front plate off and remove shim to bring the clutch gap down to .015 or so before you install and you'll be good for long time with a good used one.

That’s classic case of a $20 pnp part and laboratory being mushroomed into a $1200 job of parts and labor.

The P2 compressors seem really reliable, at 158k I would not replace proactively.

You probably have to drop the compressor To get the clearance to get the clutch off but you won’t need to break the AC system open, so no vacuum and charge needed.
