So at the beginning of the summer season the A/C was blowing hot (first time I'd ever used it) and the compressor wasn't cutting on at all. I recharged the system and the compressor cut on and the air blew cold. Voila! I thought. Wrong.

Gradually it seems like the air is getting warmer and warmer (probably a leak - not THAT big of deal). But, on the highway - at speeds of 65mph or over - there is a loud racket coming from the Compressor. It only happens intermittent (presumably when it kicks on) but it is fairly loud squealing type sound - if I hit the A/C Off button when it happens the noise stops - so that's how I narrowed it down to the compressor (as well as the fact it only started happening since I recharged the system).

Thoughts? Do I need a new compressor?

Mine started doing similar things (although it rattled, and it always did it when the clutch kicked in), and suddenly seized shortly after...

Did you also put in oil when refilling with refrigerant?

Pardon my ignorance here, but I did not - unless it was included in the Refrigerant I added (I seem to remember it mentioning something about oil). Is this something separate I should look into before the cost of a compressor?

Do you have a copy of RAVE?

The required amount of oil in the system is described in the AC section, and the type and amount depends on your model year (the compressor changed in 99, with the introduction of the Bosch engine management).

You could try adding some oil (I don't know if it's possible without specialist equipment for evacuating/refilling the system), the guy who recharged my system told me that a little bit more oil shouldn't do any harm, maybe it will cure the noise.

Did you recharge it yourself or did someone with specialist equipment do it?

Another thing I just thought of: you're sure it's not the squealing of a serpentine belt, only slipping with the additional load of the AC?

Definitely not a serpentine belt. And I just recharged it myself with one of the kits with the attached gauge from Advance Auto.

Similar sort of problem for me. Except mine was making an awful rumbling noise which turned out to be the bearings.
Bought a guaranteed good one off ebay from a Discovery 2 which was an identical model to the one off of mine(a Bosch engined model).
The reason behind buying a Disco compressor over an RR one? A third of the price of an equivalent RR one :thumb:

I have a similar issue, but actually the compressor is not coming on at all. Can't buy a Disco compressor for a 4.6 though, right?

Yes, you sure can. I did......
Compressor for Land Rover DISCOVERY MK2 4 Petrol Manual/Auto from Nov 98 to Oct 04 is exactly the same part number: AACP14-0257, as a Compressor for Land Rover RANGE ROVER 4.6 Petrol Manual/Auto from /2001 to Feb 02. Part number: AACP14-0257.
Look here for confirmation: http://www.autoairconparts.co.uk/Car-Ai ... &cat=22887.
Both items also make the same comment regarding OEM codes: This part matches any of these Original Equipment Numbers, (if shown) JPB101330 / 4472004962 / 4471705060,
Mine was purchased from a low mileage 4 litre Disco2, and yes, it fits perfectly.
