Aircon Problems

[v6mikey]

Well I wanted to say Hi to everyone in the introduction area, but don't seem to have access there, so thought I would give my 2 pence worth here.

I have bought a 2002 Sharan V6 4motion (I know its not a Galaxy, but no other decent VW forum found as yet!) due to expanding family. Very pleased so far!

The climate panel was flashing when I bought it, but didn't know what that meant, searching I stumbled across this thread.

The AC didn't work at all even the compressor didn't even try to kick in so I have just had a quick re gas at Kwik Fit. Compressor kicked in straight away and the air came through the front vents at 5 deg, very cool! Thought all was well until he said that I had a dual system and not a single as I had told him. The air started warming up very quickly, then the AC died again. So re gasses again to the correct amount for a dual system FOC, still no cold air. I don't think the compressor is kicking in now.

Will have to check tonight, apparently a tap with a hammer can make it jump in if its not kicking in.

I will keep you informed.

Firstly hi and welcome to the site.
Just wondered did they pressure test the system before putting in the gas

[bfc1001]

ive re gassed my air con and its holding charge but the air coming out is only mildly cold. does this mean there s summat else wrong with my air con or is that as good as it gets?

[gregers]

bear in mind the really decent weather hasnt come yet,iirc aircon will not work below a certain temperature?sure it might even be on this thread somewhere?

Typically 4*c, it should be working fine with the current weather - if its not then check the front fans are turning when the A/C's on, seems to be another issue!

[quote name='HJT' post='15036' date='May 13 2004, 10:31:19']We need to do something about this aircon problem. As Seatkid has mentioned on an aircon post it would be useful to see how many people have had problems. Those who have had problems also need to contact [url="http://www.bbc.co.uk/watchdog/contact/index.shtml"]BBC Watchdog[/url] to get this issue out to the public as I'm sure there are other people who don't come to this forum who have had aircon problems with their Shalaxys.[/quote]

just bought a shalaxy may b should get rid

should a fan kick in when the air con s turned on ? is this the main cooling fan in front of the engine or is there another one tucked away somewhere under the engine covers specifically for the air con?

Hi
Yes fans on inside of radiator should start soon as you turn on aircon they will automatically increase in speed if engine temp rises above normal

cheers fella. what if there as dead as a door nail? big fix ?

Hi when you turn aircon on with engine running is the pump shaft turning with the pulley or is just the pulley rotating. It doesn't sound like its pumping. You should here a clunk from the electromagnetic clutch when you switch it on.

[bfc1001]

ive just had a look and when ive put the air con on the fan hasnt moved. ive had a quick search on the forum and the main problem seems to be a relay, cant remember which number it is off the top of my head.could that be the likely cause? ill pop out and see if i can hear anything when i turn it on.....

Thanks for that.

Yes kwik fits system pulls out all the gas and oil under vacuum. It will not re fill if it detects any leaks.

Since the re fill the climate panel does not flash anymore. The fans come on the slow speed, but the compressor does not appear to kick in. A specialist is looking at it during the next couple of days. I will keep you informed.

Well I thought I would read the manual last night. (Always a good idea. ) It turns out that I only have the single AC system. The rear heater is just a heater. Way to check is if you have vents in the roof for the rear passengers you have a dual system, if you don't, you have a single system. The kwik fit guy didn't know what he was on about. So I will now have too much refrigerant in my system.

Anyway, the AC specialist says that the compressor is kicking in, but no cooling as yet. Edited April 14, 2010 by v6mikey

[Mirez]

If they've put too much gas in then the panel should still be flashing as the pressure switch will now be high instead of low and the same fault code will be logged. If its not flashing then either its leaking out or they didn't fill it for a dual system.

Either way if the system has been run with double the amount of refrigerent in it and the switch hasn't detected an over pressure condition and shut the compressor off then the compressor will probably be dead as it'l be trying to compress liquid and not gas.

[bfc1001]

im after getting to the relay box to look at relay 419 which turns on the fan but im not sure how. from what ive read the fuse box comes down to reveal the relay box, is that right? do i have to remove the trim in front of the fuse box to allow it to drop down? cheers.

Well the compressor has given up the ghost. The AC guy who looked at it said that everything works apart from the compressor. Looking for a new one now.

I don't know how long the car had not had any gas in and when the compressor was used last, so not surprised it packed in straight after a re gas.

The difference in refrigerant between the single and double systems apparently (700 for the single system and 1050 for the double.) should not damage the compressor.

Will change the compressor myself and then get it recharged.

I will keep you informed.

Hi we hope you are going to have the gas drawn off and not let it go to atmosphere

[v6mikey]

Well I thought that I should update you all.



I now have cold air!!!!!!!


Changed the compressor and the drier cartridge myself. Quite easy actually.

Just had it recharged today and bingo, everything works. (for how long!)

Didn't do anything about it at all. Just whacked the new compressor on.

It had bungs on the pipes connectors to keep out rubbish. When I took these bungs off, a bit of oil came out, so I thought i'd just try it.

Still working well. Drove to Wembley and back last Saturday to watch the match and was so glad I had working AC.

[chrispb123456]

Hi there
Just like to add when any part of the system has been open to atmosphere prior to re-gassing the system should be vacuumed this will remove any moisture that will now be present it will also remove any dirt/old oil in the system, also advisable to change drier cartridge as well, the air-con specialist will know how much oil and gas to replace, they will test for leaks and inject a fluorescent dye which will show up any future leak

Well just had a really nice trip in 80degree heat fully loaded with the family for 8 hours and no aircon !

What a time for it to stop working.

Fans are blowing warm air and do no appear to be getting to "FULL POWER" blowing only approx 3qtrs blow.

I have the electronic climate (dual) control as standard on the Bamma SE.

compressor ? or other ?

best to goto my VAG specialist garage or an aircon place? If aircon place any in the Blackpool area ??

Cheers,
Matt

I am sure all right thinking people will not want to vent any Greenhouse gases to atmosphere - but lets get real here - every system leaks at least 10% per annum - plus every time a pipe leaks or is broken gas is released - it's really not that critical. Lot of PC rubbish dreamt up by the Air Con industry to keep you going to them at inflated prices.

[chrispb123456]

Hi Bigjeeze
Yes I agree fully with you, It was meant to be lighthearted hence the rolling eye's. You also don't have the air-con guy on standby waiting for all potential road accidents, to draw off the gas before a front end impact
