Thank you. Also hopefully useful info for others.

Just been back to KF re the air con. Apparantly the system was empty, so it looks like a leak. They have refilled it and right now it's cold but if it's slowish leak apparantly their equipment can't detect it. If it doesn't work this time, they have offered a refund in line with their guarantee, so you can't complain about that. I'll have to find somebody with better gear and some UV glasses.

What i'd suggest Mark is if you get a refund from KF, find an A/C specialist and go there. Explain the situation to them and see what they suggest which i suspect will be along the lines of vac it down and check it holds, if so regas it with the correct oil and amount of gas but adding a leak detector dye and a leak sealer.

Then use the A/C as much as possible - you don't have to be cold, you can still set the heater to hot or whatever temperature you like, the heater will just be heating conditioned air instead. This will help circulate the leak sealer and the oil which will help revive the seals and keep them from drying out. That could well be all you need to get it sorted then regular use of at least a single 20 minute (uninterrupted) session every 3-4 weeks should keep everything as it should be.

If it does leak, take it back to the specialist and they should have a UV light source and be able to find the leak.

With winter on its way, the A/C will be very ueful for demisting the screen! :wink: :D
Cheers,
Dave

I may have been silent but I've still been busy.

However, I have a problem (not the air-con on the Sterling, that's on a back burner for now) with the Vitesse. All the interior lights remain on all the time; I have a closed circuit. It doesn't matter if the car is fully locked or being driven, they do not time out. I have checked/disconnected all the micro switches in the door locks (the car knows if it is locked or not), swapped out the driver unit and traced the wiring from the main engine fuse box back. If you remove 'fuse 1' then yes the lights don't work but you lose other stuff as well. What is also interesting is that you remove block C81 from the CCU they still don't go out and I would've expect them to as that is part of the circuit.

Does this suggest a faulty earth and if so how do you trace it? And before anybody suggests taking it to an auto-electrician, done that already. One told me outright he didn't want to 'eff' about with fiddly jobs (he didn't put quite as politely as that :shock: ) and another had the car for 10 days, I don't believe he even looked at it and then told me he was too busy. What's the point of booking it in then? :evil:

Is it the sort of thing the T4 can diagnose? Not been able to connect up, as it's at my brother's and what with everything going on...

Any help please, as unfortunately I'm having to disconnect the battery everytime and actually I don't like not having courtesy lights etc. Plus, I just don't like things not working as they should.

I'll have a look at the diagram later Mark and see if i can find some pointers for you try first. It may dound silly but if you pop the lenses off the front and rear courtesy lights and remove the bulbs then the two screws that hold the courtesy lights in and then refit the bulbs, do they work as they should?

Got a couple more "silly" things to check for as well but that would be the first one i'd check. If it doesn't fix things, disconnect one lamp (not just the bulb) and then the other and wait for the time out and see if either lamp sorts it out.

Somewhere you have an earth that shouldn't be between the lights and the CCU from the sound of things!

BTW, do you happen to have any sills at the moment?
Cheers,
Dave

Thanks for the reply. I think I understand where you're going with that; screws earthing to the body there? Currently the car is half stripped and no puddle lights attached but the roof ones are. I'll have a look tomorrow, weather permitting.

Sills, yes. The only problem there is the couriers have clamped down a bit and are being stringent about length. We can still courier them but I'd have to check price with carriage.

More that there is a fault in one or both of the light units and/or a wire is trapped shorting to earth - this wire would normally be the one the CCU switches to earth to bring the lights on.

Remind me of the cost of the sills please Mark?

Dave

Regarding the electrics, I have disconnected the roof lights and indeed all upper circuitry by unplugging C145, which is the block connector up behind the glovebox (removed). I have also removed EH1 (C38), the earthing point besides the steering column and still the door lights work. Presumably it means the lights are finding another common path to earth, assuming I've read the wiring diagram correctly. So how do I chase it down?

Interestingly and probably not related, with EH1 removed, the headlight switch operates the rear wiper :? !

That's the multi-million dollar question Mark! Have you done anything on your doors recently that involved removing and refitting anything? If so, has the wiring to the piddle lamps caught the window regulator and chafed causing an earth return?

Similar question elsewhere in the car on anything, the wiring goes all round the car as i daresay you've seen from the diagrams of how the loom runs. I'd love to be able to give you something more specific to say "look in this or that area for the most likely culprit" but because of how the loom is laid out and the abundance of interior lights that all share a common switch line to the CCU it's going to be a case of going through everything until you find it.

You might be able to find clues be feeling the wiring through the rubber boots between the doors and body, sometimes the wiring inside chafes as the doors are opened and closed, you could also pull back the rubber boots to inspect the wiring. Is all your interior trim still stripped out?
Cheers,
Dave

Bar the roof liner but I can discount anything above waist level now. All door cards are off, glovebox out and all puddle bulbs removed, I just have one for testing. So Dave, do you think my hypothosis and understanding is correct regarding EH1? Is there another earthing point that the interior lights can get access to (barring shorts)?

I'm sure I've disconnected the CCU previously but if I put the Sterling one in would that act as a check. I appreciate the car wouldn't start but everything else work?

It should all work with the Sterling CCU, don't forget to disconnect the battery (keys away from the car!!!) before removing the CCU but i don't think the CCU is your problem as you've unplugged it from the circuit and the lights remain on.

If all puddle lamps and interior lights are removed bar the one for testing, you should be able to make some progress with C80 removed from J5 position on the CCU. Also disconnect C85 from CCU J6b so the CCU has no connections to the earth of the lamps.

Have you got rear reading lamps in yours?

PS EH1 is the only earth header i can find linked to the interior lighting.
Cheers,
Dave

I'm going to recheck the CCU. I think I might have only unplugged C81 (J6), because I was checking the door locks. Not sure if I did C80 (J5). Been at this so long I forget what I've done. Perhaps I should write it down...
