Good morning all - after a several-month delay, I have finally fitted a new compressor and a receiver/drier to Echo, my 1984 Spirit. The compressor (Omega) is new and filled with 125PAG oil. The receiver is empty. I have not turned the compressor over as yet. My question is - what do I do now? She's booked in for a system re-gas next Wednesday - should I warm the engine through to a steady idle, and then turn on the compressor for a few seconds to distribute the oil through it? Or leave it alone until the system has been re-gassed? I have explained to the re-gas station that it's a new compressor and receiver, and they said no problem, so I hope they know what they're doing ... thanks for any advice ... Rod '84 Spirit | ||

Do not run the compressor with no gas in it. Ideally the lines and matrices should be flushed to remove the old oil. They will need to add some more oil to the system to make sure that there is sufficient in the receiver and other components. Some oil travels with the liguid gas so there will not normally be enough in the compressor for the whole system. | ||

Thanks Paul - that answers my immediate query about running the compressor or not! Not! As to the rest, I'll emphasise to the re-gas station that the compressor and receiver are new - that didn't seem to bother them, so I hope they'll do the necessary with the oil as well. Rod '84 Spirit | ||

Hi Rod I'm sure there is a switch that prevents the compressor clutch engaging without enough gas pressure ok Mike | ||
| Roderick Waite Prolific User Username: rodwaite Post Number: 145 Registered: 1-2012 |
Hello Mike - that seems very likely, on reflection! At the moment I haven't re-connected the power supply to the compressor, but I think I'll do that this weekend - to turn it on requires a deliberate action on a switch that can't be accidentally knocked on by mistake ... paranoia or what? Keep well ... Rod '84 Spirit | ||
| Paul Yorke Grand Master Username: paul_yorke Post Number: 1419 Registered: 6-2006 |
Rod, no paranoia. . How much trouble is it to leave the wire disconnected? How much trouble if the compressor is run empty. Sounds like a sure bet really  There should be a low pressure cut out but you never know what somebody may have done before you. Wire to a switch on the rear of the compressor which shorts a thermal fuse which has to overheat to turn the compressor off (eventually). The wiper switch and air con switch feel identical. I drive many different year cars and often switch the wrong one on. You must turn the compressor over by hand quite a few times. They are supposed to be shipped the right way up. However this rarely happens. Oil can get above the pistons and can form a hydraulic lock damaging con rods and bearings when first powered up. | ||

'Morning Paul! ... now he tells me! The compressor is fitted to the car, and to turn it by hand will have to be un-fitted! But without power to the clutch, how do you turn it? Must you power the clutch up? I know the unit's been sitting on my bench the right way up since mid-August, so hoping that any oil will have drained down again - it would be easier if they supplied the oil separately! Or no oil at all so you knew where you were. Anyway, I'll ask the re-gas people to engage the compressor for a very short time first time around - say one second, literally on - off, to see what happens ... hopefully nothing dramatic. The switch on Echo is handy for the left hand, whereas the (identical) wiper switch is very right hand placed, just beneath the ignition lock. The lights switch is the same type as well, but that's above the ignition lock. There's a limit to what I can explain in French to the re-gas people, you see, so thought it better to re-connect the unit myself before taking her in. And be vigilant! Maybe they'd let me stay with the car when they're ready to fire up? Worth asking ... ! Stay well Rod '84 Spirit | ||

Hi rod (posting again as last post lost again WHY???) Rod you can turn the compressor by hand (without the engine running) Just turn the front part of the clutch ok Mike | ||
| Roderick Waite Prolific User Username: rodwaite Post Number: 147 Registered: 1-2012 |
Thanks Mike - I couldn't budge anything before it was fitted, but now it's (very!) firmly mounted I'll be able to apply more torque - slacken the belts first! I'll give it a go tomorrow ... Interested in your headlights - mine are OK, but what drives me mad is the dimness of the dash panel lights. I have to stir my stumps to getting the panel off so I can check what type of led bulbs I'll need to replace them. Stay well Rod '84 Spirit | ||
| michael vass Frequent User Username: mikebentleyturbo2 Post Number: 66 Registered: 7-2015 |
Hi Rod No need to slacken the belts , the belt is disengaged buy the clutch ok Just hand pressure should be enough ok. Just turn the front of the compressor . I agree with you on instrument lights, what makes me laugh is they fit a dimmer haha Cheers Mike | ||

Hi Rod I had the same problem regards dim dash panel lights on my 74 SY1. I can really recommend changing over to LEDs. I bought my replacements from Ledlight.com. Good prices and good delivery time. https://www.ledlight.com/ There are two types of bulb on the SS, the E5 midget and as I recall the E10. All sizes are cataloged so it's just a case of comparing the measurements. On my car, since the little blue condoms on the E5 bulbs had gone opaque with age, I used enamel paint to colour them correctly. Worked great. The gauges have inbuilt blue filters. Being LEDs I did of course lose the half/full brightness facility, but that was no loss, as even on full I could barely read the gauges. I can certainly recommend the above company. Geoff | ||

Hello Geoff, and thanks - I've been thinking around these dash lights for some time, but it's one of those things you never get round to, due in part to a funk about removing the beautifully finished dash-panel! I imagine it's merely a case of removing the visible screws? I am also a bit deterred by the variety of led bulbs offered - which is the right one? Must screw up my courage ... Stay well Rod '84 Spirit | ||

With regard to the new compressor, I have been out there to turn it over by hand so that the 125PAG oil it's filled with is distributed around the compressor itself. Initially stiff to turn, once it moved it was fairly easy - I put on a pair of leather gloves and turned it over 20 revolutions, which should do the trick. So thanks Mike! Rod '84 Spirit | ||
| Nigel Johnson Prolific User Username: nigel_johnson Post Number: 151 Registered: 12-2008 |
Hi Rod, be careful with the dash. The visible screws come out also there are screws under the black padded roll under the dash.These only need to be loosened enough to clear the centre console. Regards, Nigel | ||
| Roderick Waite Prolific User Username: rodwaite Post Number: 150 Registered: 1-2012 |
Hello Nigel, and Yikes! Also Aarrggh! There had to be a catch! How does one get under the padded roll, please? Does it just pull off (carefully!) or is there a secret ritual to go through? Thanks! Rod '84 Spirit | ||

An update on the aircon system - the new compressor and receiver were fitted and I turned the compressor over by hand - easier than I had expected (thanks Mike!), and delivered Echo into the hands of the re-charge station, who did a faultless job for €82. Everything now works as it should, including demist/defrost. All my worries and fears proved to be unfounded, so thanks to everyone who helped me Get The Job Done! Stay well, one and all ...

The Aircon on my 89 corniche cools quite well. however, there is a slight whining noise at about 1500 rpm. it seems to go away over and under this rpm. it sounds exactly like a whining power steering pump. I've identified it as the compressor as it goes away with the ac off. Is this a sign of a clutch bearing or typical noise of the compressor? | ||
| Omar M. Shams Grand Master Username: omar Post Number: 1280 Registered: 4-2009 |
Dear Edward, No it is not a typical noise if it is only present at a set speed. Have you changed your belts recently? if so maybe the change in tension may be the cause. If not, check the tension to see if it is correct. Have you topped up the air con gas recently? if so when and how many top ups without the addition of oil? (ie pure top ups not a vacuum and full recharge) | ||
| Edward Mckinley Experienced User Username: ed_mckinley Post Number: 48 Registered: 2-2013 |
The belts are new and the compressor has been recharged about every two'years with r134. I was wondering if it could possibly be the belts. Is there a protocol,to,changing the belts? Which to tighten first? How tight? | ||
| Edward Mckinley Experienced User Username: ed_mckinley Post Number: 49 Registered: 2-2013 |
Found the issue. Simple re-adjusting and tightening of the belts and the sound has disappeared. Every once in a while you get lucky! | ||

Hi have an 88 Spirit and the air cond fans run slowly probably due to only 8 volts at fan on high speed and should be 12v .All speeds work but not enough output.Got a replacement S/H Spectrol fan speed resistor module from Flying spares in UK but same result would like another one I know is good to test in mine.Have checked all earths and A/C is cold. .Would happy just to work on high.Would love any suggestions on how people have solved this problem.

Hi I have been lucky with my slow A/C fans on my 88 Spirit .An electronics expert friend of mine thought the low voltage at the fans was due to internal faults in the relays .There are relays for 1 2 3 4 speeds plus overall relay next to LH shocker tower.The relays all clicked and worked so thought they were working but my expert said when he tested each the internal contacts were faulty and he could measure the voltage drop at each relay .He replaced the worst relay with another second hand one and the fans were now satisfactory but his advice was to replace all 5 relays and will be perfect so have ordered them. The new Bosch number is 0332209152 to replace old 0332204122.This can also be a reason for slow windows he said . (Message approved by david_gore) | ||

The 5 new 0332209152 relays arrived form the UK from ebay and fitted then all and now A/C fans are perfect and powerful .Wonder what other relays are operating below maximum I should replace. Electric windows all quick. Hope I can join forum soon. (Message approved by david_gore) | ||

A member who did not have any A/C fans sent me an email question and I thought I would share my answer with all. Yours may be different to my 89 but may be the same. My relays are under the hood/bonnet in the LH rear corner just behind the LH shock absorber tower and they are marked on a small vertical black metal plate next to them. There are 4 in a row and are marked 1 2 3 4 ACU fan speed which is for the fan speeds and directly behind the fan speed 1 relay is the relay for ACU fan speed control which is overall relay and could be faulty and they are all interchangeable as same number. Your other possible problem is the Fan Speed Resistor Module which is made by Spectrol and this name written on top and is just behind relays attached to the bulk head and this controls the volts to the fans; 12v high speed and 6 volts low speed. This is the more expensive item but is easy to change just plug in and is attached by two small bolts with easy access. Hope this helps and feel free to ask - can even send a photo. The relays are the same as those under the dash original number 0332204122 and the new Bosch number is 0332209152. Of course the next possible problem is the main fan switch but not so likely.
