widget Posted July 11, 2005 Report Posted July 11, 2005 Hi, I have a 02 1.9 TDi galaxy, and we've been having soem problems with the air-con not working recently - and we're about to go to France for 2 weeks - so I need to get this sorted! The garage thought the gas was low - so we've had it pressure tested and regassed - and the aircon man said all was ok. However, the car isn't getting cold inside - and I think its something to do with the compressor. I'm sure it used to clunk before when you switch the climate control to AUTO (along with a slight dip in revs) - but now you get the dip in revs and no noise. If I look in the engine bay, with the engine running and the CC set to ECON, I notice that theres a "disc" inside the pulley thats attached to the compressor (just under the altenator) thats stationary, when you hit the AUTO switch, theres a click and this disc starts spinning at the pulley speed. (and again - if you hit ECON it stops). Now I know generally these aircon compressors use some sort of elctro magnetic coupling to engage and drive them off the cambelt (or auxialliary belt) - but whats the significance of the "spinning disc"? - does that mean the electro coupling is working? can anyone tell me the mechanism by which the compressor on Galaxys is driven what should I try next ta Graham Quote

Yep, you got in one. The disc is one of a number that form a multiplate clutch, half are connected to the compressor shaft, half connected to the pulley drive, when power is applied they lock together and turn. Sometimes the clutch burns out and you lose mechanical drive to the compressor, but this is usually accompanied by a strong smell of burning (slipping clutch). As the visible disc is connected to the compressor, I would say its OK, but check it is spinning at same speed as the drive pulley (some paint marks may be called for). the aircon man said all was ok. :lol: How could he say that when the air wasn't getting cold?

widget Posted July 12, 2005 Author Report Posted July 12, 2005 The inner disc seems to be spinning at about the same speed as the pulley. Does the fact that the disc is spinning mean the clutch has successfully engaged and the compressor is being driven? ...how do you tell? If the disc spinning is not a guarantee of the clutch being engaged - is it possible to clean the clutch (I think the car went back to ford before we bought it and they diagnosed a fault with clutch not engaging - they cleaned it (somehow) and reported it working again. when I press the auto button, the revs dip, the radiator fan comes on and theres sometimes a click from the engine bay - which I assumed was the compressor engaging.

Masked Marauder Posted July 12, 2005 Report Posted July 12, 2005 Are any of the aircon pipes under the bonnet getting cold? Quote
HJT Posted July 12, 2005 Report Posted July 12, 2005 The guy who changed my condensor the other day, said he had changed several Galaxy compressors' whos drive shaft had snapped so the pulley would still turn but the compressor didn't work. Howard Quote
Guest dmc Posted July 12, 2005 Report Posted July 12, 2005 The guy who changed my condensor the other day, said he had changed several Galaxy compressors' whos drive shaft had snapped so the pulley would still turn but the compressor didn't work. Howard this is very commen.it would appear that the system is working fine as the compressor sounds like it is cutting in.are any of the pipes hot or cold(out of comp will be hot and into vehicle cold) if all pipes are normal temp(neither hot or cold) then it is 99% going to be compressor.if the pipes are hot/cold,then the fault is more than likely to be one of the motors that control the heater box "flaps" which alter the internal temp-hope that helps.

widget Posted July 13, 2005 Author Report Posted July 13, 2005 drat - compressor pulley is going around, but either pipe out of the compressor after a few minutes shows no sign of being anything other than the same temp before the compressor was started. bloke who did the regass came back today and said basically the same thing, shearing compressor drive shafts are very common on galaxy compressors. He said the compressor was probably the weakest part of the galaxy - and then we told him about the auxilliary heater! :D he quoted Quote
SharanTDICarat Posted July 13, 2005 Report Posted July 13, 2005 ...air-con bloke said we should have bought a Sharran! ;) Graham Same car different badge just depends on what badge you want I suppose.TAM Quote
HJT Posted July 14, 2005 Report Posted July 14, 2005 Thats a shame, Aircon Direct are in the southeast and don't go that far. Howard Quote
widget Posted July 14, 2005 Author Report Posted July 14, 2005 anyone used these guys? http://www.bba-reman.com/content.aspx?cont...rcon_compressor ...turns out the compressor our aircon guy was offering was a Hella one, and according to their website - they're all refurbished - not new! - something which the bloke neglected to mention funny, I was just thinking of making sure I ask for the old one after it had been replaced - so I could take it apart and see what had broken - but of course - I bet the bloke would have wanted to keep it - so he could exchange it and get a wedge of money back - while charging us Quote
widget Posted July 14, 2005 Author Report Posted July 14, 2005 ah - ok - looked more closely - its "re- manufactured" On the www.fordpartsuk.com website - a new ford compressor is Quote
