  1. Just had mine completely refilled with the R12 equiv. 1300g If its just a top up watch the sight glass and do by eye. See here..... Bottom of page.
  2. Wow! My poor S4 lives outside and is driven 12 months a year and has no where near that amount of corrosion. The before pictures look like they have been continually sprayed with salt water for years.
  3. ‘‘Twas a loose connection on the sender. I must have nudged it at oil change.
  4. A full day today sorting all the HVAC system and reversing some heinous bodge work by a ‘Lotus specialist’.Just been for an extended test drive on a warn moist muggy evening with air con blasting out resulted in almost frozen face! Result indeed. All the work under the dash seems to have sorted several annoying squeaks and rattles too. Bonus.
  5. Thanks for all the help gents, we have a winner!!! So here is the answer to the puzzle. On a previous repair on behalf of the p.o for which I have the receipt from a 'reputable' Lotus specialist they had taken the recycle flap out of the loop and removed the T-Piece (the elbow at the recirc. actuator was crumbled and obviously couldn't be arsed to skin the required knuckles to get to it. It transpired that when they put the remaining bits back together they used the wrong vac valve. I swapped that back, reinstated the recirc pipe and T piece but STUPIDLY assumed when said specialist had done the bodge they had at least put the pipes on the vac valves the right way round! The valves have a one way release valve in them and were pressurising but not releasing when the dial was turned. Escapes diagram proved invaluable and it was only during a passing thunderstorm that I revisited it again and noticed the problem. Now fully operational HVAC with Air conditioning Thanks again to everyone who has interrupted their Sunday to give advice on this. Better go and get the seat put back in now and go for a well earned blast round.
  6. OK all plumbed in correctly now but still having issues. Once the valves have been opened and pulled the front flap down for outside air and the vent flap for windscreen demist is engaged when you close the vac valves surely there should be some kind of de vacuuming happen to allow the recirc flap to raise and the eyeball vents to be fed with air?
  7. Not my Halfords Barry. Managed to get some 3mm ID vac hose and that's done the trick. I think the outlets from the Vac valves are on the wrong way round. Luckily I haven't put the car back together yet. Scone and a cuppa time. That diagram isn't for my car Ian. Nos 18 and 45 are not there.
  8. OK, heater fan shroud removed and actuator located. Where the hell am I going to fine 2m off 1950s vacuum pipe and elbows on a Sunday???
  9. Found it! Took the seat out and assumed the position. Another 'Lotus specialist' bodge. The lower of the two vac valves has been taken out of the system as has the t piece. The vac pump is only supplying the vent flap which when up to pressure is engaging the flap but when you turn the rotary dial the vacuum has nowhere to be released to so the flap cant return to the eyeball vent position. Ian. Where does the outlet from the disconnected pipe connect. I can see its another vac actuator on the fan housing but cant see it under the centre console. any clues please?
  10. Ok got impatient and started stripping. Fairly sure its the heater flap valve. I can see the rotary cam next to it turning but the plunger on the top is not moving. At least its not in a reeeeaaly arkward place to get to!!
  11. So a quick update. Checked the vac pump run time on the car and its around 30 secs to stop. However if I move the vent Past 3 o'clock the pump starts up again continuously. Before I start taking things apart can anyone suggest which elbow might be responsible?
  12. Thanks Ian. The trunking is all in place as when I start the car before the vacuum has chance to build I get cold air from all the eyeballs. Once the vacuum is present I only get air from one. Very strange. As an aside I was contemplating a V8 but read 43 pages of Barry's V8 woes last night. Decided to pickle my own eyeballs instead, seems less painful.
  13. Having now got working aircon I have noticed that, as expected until the vac pump is up to pressure all you get is cold air from all the eyeball vents and no adjustment to the other vents i.e functioning as expected without vac. Once the system is active (for want of a better phrase) and the vent dial is turned it cycles through its various settings however when turned fully anti clockwise to the windscreen symbol only the drivers right hand eyeball emits anything. Its as though the dial isn't turning the full distance. Is there any kind of adjustment possible on this via a cable possibly to get them all flowing? Also I note that the temp dial doesn't seem to vary the temp much on the footwell, windscreen vents. I get a range of slighty warm to a bit warmer than that. Never cold, never good heat. any ideas anyone??
  14. Speaking of fresher I never thought I would say this but I now have ice cold air con!! Having been quoted daft money to go through the system and re-gas with the correct gas I had been putting it off for a fair while. Then I remembered having an older 911 done by Geoff at at Chesterfield. Gave him a bell to confirm he still had all the old equipment and popped over this morning. Geoff is a bit of a petrol head himself and genuinely has a passion for working on less common stuff. He went through the whole system, sorted a wiring issue and re gassed the system for £70. It would have been cheaper but he needed to do a full re gas and Esprits hold a shed load of the more expensive stuff! He explained everything as he went and talked to me about the sight glass under the ABS unit cover behind the headlight. If the system is fully charged (or completely empty) this will appear clear however with the engine and aircon running you will see a pulse in the fluid as the system operates. You will also see an occasional bubble. If you see lots of bubbles as the system operates it indicates you are getting ready for a top up. The joy of this system is unlike new cars which have to be emptied and a full charge added the technician fills using the glass as an indicator so can 'top up' with however little you need (meaning a cheaper job). Geoff also can repair hard and soft aircon lines and components so well worth bearing in mind for any older car with hens teeth parts.
