here is the reason why I was talking about fan control module - as the clutch seem to get it's 12V from the fan control module........just wondering if that might have the relay 13 "integrated" somwhow but I guess I'l just get hold of one and try.

I found one having +12V - the black/yellow wire on the picture below: the harness: other side: control switch:' and the missing relay:

I'l check - I doubt I'l get anything as the relay isn't in there - wonder why they have removed it in the first place - nothing amazes me with people and car electric anymore. Just found a speaker wire that was cut - then re-fitted with a cable connector boot with 0.5m cable connected - into another boot and about 0.5m cable then going back to the other part of the line that they firstly cut........lol....

atleast been able to verify that the clutch works by supplying 12V to it. The harness that goes into the control valve is in my car a square harness with 4 wires. (in bentley it seem to be a harness where 4 wires in a row), but to me it seem like the resistance between 2 of the terminals changes slightly if button "norm" is pressed, and then getting lower when the "max" button is engaged. Unsure which of them that can be "jumped", and also unsure where it goes further. any idea where the clutch get's it's feed from ? - does it come straight from the fuse box or?. also the 2 30Amp fuses in the fusebox seem to be ok............I'm starting to wonder if it might just be a missing relay.........any idea how this relay number 13 can be "jumped" - just to check output ?

To me it seem like the bentley talks about jumping the harness of the fan-control module to get power to the clutch - I think these 2 systems are interconnected somehow - as if the car get's to hot it will shut of the A/C system to prioritize cooling of engine........I'm not sure about this though - it might also be that the jumping they talk about is something on the pressure control valve of the AC system. I'm going out now to see if I can make any sense of this...lol....:)

The relay's in question is the ones with number 13 and 56 stamped on em - according to bentley nr 13 is supposed to sit in slot nr 1 in the fuse-box thingy. But I'm a bit unsure if it might have been relocated (due to this car being a late model) or removed from mine.

Found a wiring diagram for a 94 - and if I read this thing correctly that control module is here, but also seem that there is a relay inside the car: http://www.corrado.com.pl/elektryka/corrado94.pdf it also says one can jump terminal 1 (T4b/1) and terminal 2 (T4b/2) to engage the clutch (page: 87-38 - bentley). but unsure if they mean to just jump the harness plug of the fan control module or if it's on the pressure switch harness they mean - any idea?. Also if you look at page 2 there is where I think I see the control module - and also a relay inside the car (at top)?.

I have also bad feelings about some of the wiring gremlins in here (just starting to have a look at em after the rebuild) - I'm amazed at what people do when it comes to wiring........just have to get it all sorted out (it's not all that bad - seem as most of it have to do with the stereo wiring) - gona try to solder back the wires they cut and "clamped" together...... Any idea if that number 13 is an expensive relay or?. Also am I supposed to have a 56?. If the wiring is in the bentley I have it - but feel free to tell me the pages that covers it ;)

I once was told that UK corrados were dealer fitted aircon, so unless yours was imported, it won't (probably) have an OEM a.c. :( There is a connector attached to the radiator, which (in my car) is for a.c. clutch In addition, if you look under-behind the dash on p/side, you will see the recirculated air flap and you may even see (hope to!) two wires which are for the a.c. evaporator temperature switch. One of these two wires should show +12v when you switch on the a.c. I'm in Norway - so my C is a German import - so it's factory fitted... I'l try to get up some pics in a few days - if you happen to have any pics of these parts also, would be nice if you eventually could add some pics here :)

is that the connector that sits beside the radiator?. Mine doesn't have a relay nr 13 - or it's hidden somewhere, the nr 1 slot in the relay box is all empty :( (the system is an OEM - original fitted R134 gas system).

Can anyone tell me if 13 is supposed to be in POS 1? Also - just to make sure, I presume the relay isn't in the engine bay? (can't remember what it's for but it's that big "lump" with 2 fuses on sitting in front of the water "tank") - any idea if that might have anything to do with the A/C?. There seem to be something wrong with wiring/fuse/relay as I can't get 12V to the compressor clutch thingy....:(

Anyone got a picture with all relay's and fuses installed from a late VR6 with A/C ?. I'm starting to think I might be missing some relay's for the A/C (can't find number 13)...:(

Also might want to feel with your hand over the paint, and see if it's smooth as glass - if not you might want to consider calying it before polishing and waxing ;)

I would guess you still would get some swirls etc, have you tried to polish it and then wax it?. Also, maybe check to see if it needs to be clayed ? (not sure it will need it if paint is totaly fresh)....

ahh, ok, thnx for reply guys - I'l leave em as they are then :)

ahh, ok...so different design on em or?

If you let the slave cylinder piston come out too much I'm fairly sure it lets air into the system, if you've just had the clutch done this is a strong possibility. You should try your best not to let this happen but I'll be the first to admit its easier said than done and I ended up with the same problem, I bled it and problem solved. So as said earlier bleed it again before splashing the cash. You know what - now that I think about it, I actually disconnected the slave cylinder (from the gear box - not the actual hose), when I mounted the bracket that holds the cable to the fans.....:) Didn't think that would let air in, but that must be the case, thnx m8, bet this is the reason :) I mean I have a new slave in the workshop, but no need to install it if the old is good :)

I'v been bleeding it quite a few times, even pushed back fluid into the bleed valve to get rid of air. Might it be that it still some air trapped, that slowly migrates when it's beiing used?....

yea, but can it fail to "release" the gear at all, if wanting to stop the car :)

is there any danger using the car as it is - can it suddenly be without clutch or? (or will it work when pumping it?).

any way I could check that ?.

degreased it, washed it, polished it and finaly vaxed it. :) Starting to look like a real C again :)

Anyone know if the clutch should go "dead" when the car have been sitting some days without battery connected?. I had to pump it a few times before it worked again. Also I think it feels very "soft", even though the system have been bled, is this maybe normal with a new clutch and new throwout bearing?.

yea, I'l check with the cluster I have in the Passat VR6 - it's not the same motometer/VDO, but they are interchangable :)

Any idea what might cause it - I did a fix on the fuel gauge (same gauge), and that part of it works now, before it sat to 0 all the time....IIRC it was some bad wiring on it. Is the temp gauge also possible to fix?
