Thanks for the input Tommy, Dan and 95.

Tommy, I guess I'm in exactly the same position as the OP in that link, but it doesn't look as though he posted a solution... darn.

Dan, I found this ( http://cgi.ebay.co.uk/EZ-CHILL-DIY-AI ... ain_3&hash=item483a439ba7 ) on e-bay and it looks as though the guy is in the UK and will ship to Spain, but digging deeper into the FAQ/link ( http://www.id-usa.com/pdf/inst/RKR-7.pdf ) he sends you to, it seems I would still need to do a conversion of seals etc first (if I'm puuting the info from the FSM and his FAQ together correctly). So I'm still trying to find out what particular seals and other parts are needed.

I tried your suggestion and forced the compressor clutch to engage by putting 12v across it - the comprssor pipes and the vent air flow did get cooler, not as cold as normal because I got a bit panicky and didn't let it run for long.

I check with a couple of local garages and I've been told that R12 isn't used here anymore, unless I find a rouge who will do it illegally, so it looks as though the conversion of seals etc has got to be first on the list.

A bit more closer inspection and you and 95vette are right, I'm sure the compressor front seal is shot - there is more signs of grud/leakage across the inside of the hood, all in line with the front of the compressor.

I'm not too keen, or financially flushed, to want to buy a new/recon compressor, which seem to be around 400-500US plus shipping and import duties (which are a killer), so I'm looking to see if I can find parts to do the repair and conversion.... anyone ever done this and have any tips/suggestions and also a list of parts needed for the conversion - the net brings up a few hits on earlier models, but can't find anything for a 93.

Thanks again guys.
