Default Air con leak?

My air con has not been working for a while now, which has been difficult in the heatwave, so the other day I went to a local chain place (F1 Autocentres) and had it re-gassed. Whoopee! Running nice and cold. Now, today, though, the first time I've used the car since re-gassing, it's back to blowing ambient temperature air. So I'm presuming this is a leak?

Is there a typical place such a leak occurs on the 75s? (Mine's a 2002 Club CDT Tourer). And what kind of place fixes this sort of thing? Mainstream garage or do I need a specialist? Slightly dreading the cost of this, and hoping parts might be obtainable from breakers, but may not be such a great idea for this?

Hi John,

I had mine fixed at 'Panks Auto' on Heigham st. Just round the corner from F1.

Cost £71 including a Nitrogen pressure test to test for leaks before re-filling the system.
When filling the added dye in case it leaked in the future.

The condensor is the first thing that comes to mind especially if your s is original. I'm surprised F1 didn't do a vacuum test to check for leaks before regassing. Might pay to query this with them first or find a motor aircon specialist who could do this and trace the leak for you. If its condenser failure its bumper off job to fix which should be straightforward enough for decent independent garage or aircon man. Rough cost of unit itself £100, I bought mine a while back from Jules together with O rings etc. My first port of call would be F1.

It's getting common now as our cars age, the condenser would be my first thought. Just done mine

Thanks, that's handy. Panks are pretty good. What did they actually fix?

Thanks. I went back to F1 and they said theirs was an automated re-gassing process which didn't check for leaks. The guy said that if I got the leak fixed elsewhere I could go back there for a re-gas free of charge.

So where would I get a new condenser, if it turned out to be that?

Fellow Wedgwood Blue owner here. What a colour that is!

Hi John,

The aircon hadn't worked for some time, & due to covid I wasn't using the car so ignored it.
In Early May I went in a had a chat, they did my wife's car a few years back after Fast-Fit had... well it lasted a week! (neighbor recommended Panks).
Anyway they said they would do a nitrogen pressure test first to check for leaks, then if all was good they would re-fill + dye.
Booked the car in with them the following week, been ice cold since.
I've found them to be very helpful twice now.

Took my son's Insignia in 2 weeks back for the same treatment. No gas at the start, refilled, but no cold air. They spent 2 hours chasing the fault but were unable to trace the fault as they weren't able to interrogate the aircon control system. Ended up in Vauxhall Gt Y. to diagnose a problem with the control side also. Should get that Back Monday.

Aircon pipe possible leakage place is the bottom condensor-compressor pipe due to rubbing against a tensioner. Turn the frontwheels, lay down and have a look with a torch, very visible if this would be the problem.
