Put 12v direct to compressor, if clutch kicks in I would suspect a leak in the system. Only correct way to test for leak is fill the system with a nitrogen /air mix and use a sniffer probe. A job for the experts. As said, 12v direct to comp.

Sounds like this guy's a cretin with no understanding of how air con systems work. Avoid like the plague, IMHO.

If the compressor hasn't "kicked-in" then surely he hasn't had the opportunity to test it?

If he's vac'ed the system out, checked for leaks and refilled, as he's legally supposed to when servicing an air con system, he will know that there is adequate pressure in the system. Next check is for the electrical side of things as there is clearly no supply to the compressor clutch.

Only if he'd got the compressor running would he know if it was working or not.

Sounds like you need to take it to someone who knows what they are doing.

Glad someone else has said what I hinted at!

As I said Duggs, go to Kesgrave Cars. They aren't the cheapest but they do know what they're doing and were happy enough for me to watch and talk me through it That's why I know they're doing it right

Will do Paul.  Spoke to them earlier and they said to bring her in and they'll take a look at her for me.

Will try to get along there tomorrow but saving for a journey across the pond in 6 weeks so money is really tight. NOT helped by throwing away £30.00 to the "experts" up the road...

Unfortunately you have been well and truly "ripped off".

There is an Air Con expert set up in Swindon .. Halls Electrical... doing a diagnostic check ... they connect to the system and check the pressures - Static and running (which I believe is a better check of the compressor) - vent temps, and run a UV light all around....... This is free.

After they've done that, if you want/need a regas, they purge the system and weigh the gas removed, vacuum for 30 minutes (which does a leak check and dries the system) then regas with the correct weight of gas, oil and UV dye... 

The first weight check (gas removed) also gives an indication of if the thing leaks....

all for £39.99 and about an hour.....

Well worth it IMHO

Be carefull,re my posts end of May,I went for regassing twice,paid twice,and was degassed twice So I then went to a specialist firm who work on HGVs and asked for an air con diagnostic. Finished up needing a replacement pipe that has on it the inlet valve that was knackered, this took 3 weeks to arrive from Germany, to me that was a proper sickener, and today I went to have the pipe fitted and journeyed home with a cold car at a cost of £264.68 so with the £45.00 & £40.00,regassing charges not cheap.I think that when  I first had it regassed its possible he damaged the inlet valve,the second firm said there was a blockage in the system.Sorry to be the bearer of bad news but I thought the info could help you avoid my problems

As RobG says above.  Normal failure on a/c compressor is the clutch.  Easy to check with or without gas in system.  Remove electric plug from compressor and put 12v across compressor terminals.  If clutch ok you will hear clutch kick in with a loudish thud    No thud = compressor breaked!!

So let me get this right your air con was working until 3 months ago?
When you put the climate on eg 21 on the dash or air con LO nothing happened?
Like already said when the gas pressure drops the pump won't kick in.
So gasman filled it up to 950 grams.
Did when you pressed either the climate or air con on did the revs lift 100 rpm? Could you see the pump spinning? Was it warm, aired  or cold?
Perhaps checking the rods in the footwell maybe worth ago as mine was off on the drivers side....

[Kaycee]

may be daft answer but you only mentioned the auto switch you have to press the eco switch so eco symbol goes out forgive me as it can be confusing to some of the so called experts like kwick fit i got a similar situation with them saying my system was fubar but he had not pressed the eco switch if i ad been a  youbg woman or some one who didnt know i would av forked out for new condensor or wat ever

Your comments are correct sir. Unfortunately I wasn't there after the re-gas. They said once filled, the compressor wouldn't start, no click, no change in revs.

In fairness, now I think about it, I've had neither happen for a while now. Before their did it, recently I'd select auto or low and I still wasn't getting the click or revs change. Assumed gas was getting low or gone so took it to them for a re-gas, from which they've concluded the compressor is flubbered.

Perhaps foolishly I don't use AUTO very often....just change the settings manually as and when I need too.

Heating works a treat by the way, no problem on that front.

Thats going to cause issues, mine is always left in auto. If its not used the bearings will dry up, and when you come to use it, bang

Maintenance
In order to ensure continuously efficient
performance of the electronic air conditioning
system it must be switched on once a month
for a few minutes, irrespective of the weather
and time of year, with the cooling (cooling
compressor) operational.

As said .. this stops the bearings seizing, and also allows the "drier" to remove moisture from within the system. Moisture + refridgerant = corrosive mixture that does the internal workings of the compressor no good whatsoever..

I just leave mine on all the time ..
