Noticed over the last few weeks that even when my air con is set to Lo, the air coming out of the vents is not cold at all.

Had it regassed about 8 months ago. After that it wasn't great but slightly better than before.

Does it need regassed again or is it a bigger problem.

Got an 07 2.2 diesel.

Thanks

Take the caps off the A/C pipes, and press in the valve, should fling out some gas, just press it quickly, if theres none in it you have a leak in the system somewhere. Most likley the culprit will be the condensor.

It is such an easy fix really
I went for the gm relay because it was the cheapest and perfectly adequate for the job , I would say is if you have an empty system do check the pressure switch which is located on top of the high pressure pipe next to the engine , if that is faulty it will also hold off the compressor and fan .

Thanks for the info and the video @cjrshop - really helpful.

I've checked the valves and there is gas in the system.

When I press the A/C button to turn it on I can only hear a click in the engine bay, can't really hear anything else.

Have ordered te GM part from ebay - £1.95 will stick that in when it gets here to see if it makes any difference.

Any ideas what I need to check next?
Thanks

Is the relay okay? , if you have gas (definitely ) you can disconnect the pressure switch just pull off the electrical plug on top and bridge out the connections if the compressor and fan come on you know that the switch is faulty .

Sorry, don't know what you mean by 'bridge out the connections' ... could you explain.

Yes sorry so if you follow the high pressure a/c pipe down from the fill point you will find a black electrical plug on top of a pressure switch ,with the a/c button on in the car , take a small piece of wire and bridge out the electrical connections if all kicks in fine you know you also have a faulty pressure switch

I've located the switch you mention and even managed to get my fingers on the top of it.

Can't seem to get it off though. Even if I did I doubt that I could do anything meanigful with some wire in that small space.

I think I've reached the limit of my mechanical abilities with this one :laugh2:

I'll try the new switch I ordered anyway and see if it makes any difference.

Thanks for your help.

It does unplug very easily , and once unplugged you can get the loom out of the bay and do the cable bridge very easily , your just fooling the system into thinking the switch is pressed

EXCELLENT - made it look easy, which generally, it is.

I'm at the relay stage - here's hoping!

I read that the original European Omron relay was ditched by Honda in favour of the Mitsuba one from Japan.

No surprise that the Mitsubas are £24 delivered!

Just found this: GENUINE HONDA AIR CON RELAY CIVIC JAZZ CR-V FR-V ACCORD 39794-SDA-A05 | eBay
Don't see the packaging and labels, but it's £5 cheaper than I paid from a Honda dealer - on Ebay.

Al.
7G's have about three of these relays in the fuse box and there's an abundance of them in the Scrappies... I took one out excluding the one in my pocket and the guy just waved me on Free of Charge.... Good luck though, I thought the Relay had fixed mine but it hadn't.. Traded the old girl in since with a slipping clutch, goosed manifold and very intermittent A/C

Didn't want to start another thread but recently my air con has stopped working. Over the past month or so when I had the air con running the air con fan/compression (noise you hear when switch the air con on) was coming on more often until it was nearly always on, now the air con doesn't start up at all

I just checked the relay with another I had and it made no difference so it's not that.

Would that possibly just mean it needs re gassed? I don't know when the last time that was done :S
