Title: Air con not working
Post by: Nick27 on 20 June 2013, 21:23:50
Hi,

A/C is not working on my car, even though recent refilled the gas. I spoke to the garage who refilled the gas on the phone he said that there might be a leakage on the air con radiator. is it the case really? Every summer I have to get it refilled and last time I did asked the garage to check whether there is a leakage and they confirmed no leakage.  :-\

Can you guys please help.

Thanks,

Nick.

Was a pressure test done?
This was the problem with mine.

When mine wasn't working I thought it simply needed charged. It still didn't work and I complained. Apparently the pressure test is not part of the process, but the leak rest may be.
In the end a little valve needed replaced once I had requested the test be done and the problem then confirmed.
Just a thought  :y

Hmmm....i should then ask to have a leak test around the valves. :y

A/c needs to be pressure tested with nitrogen to find if there is a leak,then tested with dye to find the leak.
Condensors seem to leak at the bottom corners,or near the battery tray,the L/P valve is just a normal.tyre valve core, the H/P valve(port) is 13277003 £4.19 on tc.

If its a slow leak - ie takes weeks before it stops working - pressure/leak tests won't show it. They should put dye in it, and that will reveal the leak when its leaked most of the refrigerent out weeks later.

I have two of them,but neither of them have been used on a car for at least 6 months. I have heard it said that the seals can dry out if they aren't used,so it might be a bit of a gamble tbh. Might be worth asking for opinions before diving in ,but I only want £20 for one,and your close enough to not have to pay the postage,which would be expensive for something so heavy.

"Gone" meaning what actually?
Yep, seals can dry out if A/C not used regularly.

Selonoids not working in the compressor.

I also noticed that when i switch on A/c rpm normally goes down a bit but not anymore.

What test did they perform, 12V direct to compressor?

Not sure but they had the machine attached to the valves where the gas is refilled from, he told me that he injected an oil to perform test. Sorry not a very technical person  :-\

Doesn`t sound very knowledgeable ???
To confirm if the compressor is knackered you need to unplug connector and apply 12V & 0V to contacts and see if the clutch engages

Has been known, but seals usually dry out due to the effect of surrounding heat (engine/exhaust) and compressor being switched off for very lengthy periods. Removed from car and adequately stored shouldn`t really present any problems

Easy enough to do Nick. Jack up N/S front (axle stand) and either run extended cables from battery to comp. or connect 2 probes to plugged in battery charger croc clips and touch relevant inputs on comp
