Hello,

Well it lasted a year!!

The Air Con has stopped working in my 1994 4.0 Coupe. I think it's the last type, fitted with the Sanden SD7H15 compressor and charged with HFC 134A.

Brought my XJS a year ago and all was working well until a couple of weeks ago. The compressor clutch is not engaging, I've checked fuses and relays. Blowers, controls all working OK.

Hoping it just needs a re-charge, but would like to have a leak test at the same time.

Has anyone used a air con company or garage in Oxfordshire or Berkshire they could recommend?

Thanks,


Mike.

Hi Mike

My brother recently used a air/con specialist in Carterton near Witney if that is any use to you let me know and I will get the details for you.

Sorry can't help geographically, but had aircon trouble on my similar car. The leak was so small that it could not be detected using the usual dye, but the garage then got a new testing machine which uses nitrogen and it was obvious where the trouble was. Best of luck fixing probably the most annoying system on the car. I wish I could afford to convert to a proper modern installation.

Hi,

An update.

Found a great guy based in Didcot - Polar Vehicle Systems http://www.polarac.co.uk/

Mobile service, Paul came out on Friday. Did a pressure test, vaccum test and leak test. Really took some time on this, over an hour and a half. All to his amazement were OK!

Paul has a lot of experience with Jag's. Our cars, Aston Martin's and Volvo's always present the biggest challenges. in 1991 he had an XJS as his company car when service manager at Lancaster Reading.

A recharge and re-oil and all seems well. For now!

Cheers,


Mike.

Knew it wouldn't last!

Got a hissing noise inside the car today and little or no cooling

I'm guessing the full charge has stressed the system/seals and 10 to 1 it's the evaporator!

I'll get Polar Air back anyway just to confirm the worst, and then decide how important AC is.

Recharged worked for a couple of weeks and then a new problem arose whereby the compressor would only kick in for 5 seconds and then stop for 30.

Think I have finally got to the bottom of the problem.

Thanks to a recommendation from Michael Burnside, I took the car to A.C.R.E. in Caterton.

20 years experience, including all jobs tackled on our cars.

Air leak at expansion valve, then the Receiver/Dryer had broken up and blocked the expansion valve. New parts fitted and 6 weeks on all seems as it should be.

I can recommended their services. Parts, labour and all work carried out on my driveway for just over £200.
