  1. 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.

  2. 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.

  3. 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?


  4. 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.

  5. 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??

  6. 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.

  7. New bits all fitted last week along with sorting out the centre rad fan (slightly seized so occasionally blowing a fuse and getting 'Fan Fail' warning'). The new head unit looks very in nice with no nasty flashing graphics and the like. Now have iPhone charging and play, DAB (thank god), Bluetooth connection for Android and Apple and hands free phone with voice control. The higher power head unit runs the Infinity speakers far better.

    Front number plate was looking very tired so popped a new one on. Car looks much fresher now with lip and plate.

  8. Give the rad pack a good coat of looking at. Check for  and remove debris and sort any corroded connectors.

    Make sure you use ceratec lube or similar to coat the fastenings when you put em back in the rebuild in case they ever have to come off again.

    Don't overtighten the corner fastenings on the corner of the bumper, they strip the nuts glassed into the body quite easily.

    Replace the horn if its on its way out.

  9. Thanks. Not done much on the Esprit over the last year but I have a few little jobs I will be attending to and posting on in the coming weeks. Postie bought some parcels this morning so I can crack on.

    Have a retro motorised mask head unit at the moment but can only listen to a cd so many times. Taken the plunge and upgraded to DAB, hands free etc head unit. This pioneer unit looked fairly understated so should look in keeping.

  10. Finally bit the bullet and ordered the new heater control graphic to replace the crumbly one in situ at present. Bizarrely she is currently running better than ever and barring a mystery clunk over speed bumps I really don't want to take spanners to anything and temp the Norfolk gremlins into showing their faces.

    Guess ill just drive and enjoy instead. 


  11. Well the 944 has moved off to its new owner. He lived nearby and had watched its rebuild before popping in with a cheeky offer. So while there is space on the drive I thought I would have a day on old Yella.

    Oil and filter change (no pics needed im sure)

    Fluids topped up (chargecooler seems to have a slow leak somewhere as this needs a quarter of a pint every 6 months or so)

    Still getting a very faint aroma or petrol on occasion and I was aware that when replacing the breather pipes I had left the ones connecting to the canister alone as they appeared sound. Another inspection showed cracking in the pipe from the anti roll valve to the canister so replaced this. The air intake pipe seemed worse for wear too so fitted a new one and re-routed this to the rear of the car to rule out any blow back of vapours.




  12. watching Catchpole hold the over steer on throttle in standing water makes me realize that even though my S4 has been improved dramatically with new shocks and set up it still has a long way to go. Any throttle mid bend in the wet causes massive over steer. New rear tyres are the first port of call as the Avons currently on are about 9 yrs old. Love how much more aggressive the 300 Sport looks. 350 sport never looked that purposeful.
