A/c not working, wondering if anyone has any rough idea , the compressor isn't spinning ethier if that helps, I've checked all fuses, and none seem to be blown * but I don't know which ones are exactly for AC/compressor *

Thank you for the tips/help =)

Hello, I've had this headbanging issue last year. Unfortunately, "AC specialists" just regas your system (blowing your money and a chunk of the ozone) because that's all they know. Wheel the machine over, have a coffee and stare at the Pirelli calendar girls while it evacuates the system and pumps the R134a in, charge you money and that's it. I had three of these done (with other useless tinkering) so it's a good idea to find all the problems (may be more than one) in one go as any replaced part means another evac and regas.

If your compressor clutch isn't spinning, then you're not going to get a/c in the cabin. Need to find out why that's not happening. When you're doing a steady speed in 5th and you press the AC button - apart from the button lighting, which doesn't mean much - you should notice a slight drop in the revs or a bit less power going to the wheels, even if the AC's not cooling the cabin. If so, at least the instruction is getting through. First thing I'd check is the connector to the compressor. It's grey (often with a blue clip) and looks a bit like this one

Preferably, have someone at the wheel with the engine running while you have the bonnet up and staring at the compressor clutch. Get them to push in the AC switch. Nothing happens? Give the grey connector a good waggle, tug and thrust. You might find that the plate starts spinning around. If your assistant says "getting cold air now" then happy days. This connection can be a bit of a dud and might be why the instruction to spin is not getting passed on. Take my word for it, after the first speed bump or jolt, it'll go off again so get the connector replaced or have the wires soldered on and waterproofed. I hope it's just that - it would be a result.

If it just refuses to spin at all, and fuses F31 and F45 are ok:

then you may have a seized compressor. Whether the replacement is new or used (I bought a used one last year, and have another for backup, about £25-30 from ebay) the system will have to be evacuated and regassed after fitting. Don't follow my example, pay all that money and get 4 days (or less) cold air and back to square one. It's well worth checking for leaks before this, just to be sure. Ask the previous regassers, did they add a fluorescent dye to the R134a? They really should have, but might not have. If so, in a darkish area with the engine running, you could have a look with a UV light. The common places for leaks are the condenser (in front of the rad), the rubber pipes and junctions to the metal bits. Alternatively, given that you've just had it regassed, pressure gauges (I have a set, if you're in NW England or ask the previous gasser to re-check) should tell you if the refrigerant's still in there. The condenser's the expensive leak. I had to replace a bit of pipe (£20 ebay used item) and the condenser which was a new Valeo (the cheap ones are not very good) at >£160.

If there are no leaks, then a replacement compressor and a regas should give you a reliably cool cabin for quite a while. Keep updating with what you find, I'm not super useful like the other people on the forum but I've been through all the things that can go wrong so I might well recognise a symptom.

My AC has never worked, I never thought to even check the fuses (I should know that's the first place to check when anything doesn't work!!). I just assumed a seized compressor and I've just lived with it. I wonder whether you might bring your gauges with you when you're over this way next...? :unsure:

Shall do, remind me before I set off. HST, you've had no a/c all the time I've known you so I'm pretty sure the gauges will tell me that your refrigerant is nowhere in the system. Doesn't take much effort to find out, though, so I'll happily take the excuse to use them again. Having got a working a/c (three of them, actually, it's important to me) they tend to sit in the case doing s'dall. I bought them so I didn't get BSed any more by the 'specialists'.

An AC system on a car is literally one of the things I know absolutely nothing about, so even if we get the "thingy" engaging/spinning, you're probably spot on with it having no gas in it regardless!!
