My air-con stopped working along with speed setting 1 (which I didn’t notice at first because it’s so quiet and slow).
It turned out that the "blower motor resistor" (thing which controls the fan speeds) also deals with activating the compressor when you press the a/c button on the panel.
It could be something on the resistor block that’s blown preventing your compressor from activating. (£20 from pug)
Also,
Do you get the green light come on when you press the a/c button?
Can you hear the compressor clutch engage with the engine?
Does the radiator fan start spinning when you press the a/c button?
When my air-con wasn’t working I had the light come on but the clutch didn’t engage and the radiator fan didn’t spin.
Hope this helps.

if there's a leak then what does the garage has to do?
fix the leak?
do they fix the part or replace it?
never had to get it done tbh. Peugeot re-gassed my system and told me they can inject a dye to check for any leaks

yeah the ac light comes on, what is a compressor clutch?
#19: Re: Got Air conditioning Re-gassed but still no cold air? Author: MrrNoName, Location: UKPosted: Mon Jun 25, 2012 7:05 am ---- The compressor which runs the air conditioning is driven directly from the engine in a mechanical process.
When you switch the air conditioning on or off an electronically controlled clutch engages/disengages the compressor from the engine.
If the clutch is working and engaging/disengaging the compressor you will hear a "clunk" and the engines revs will change slightly for a split second when the a/c button is pressed (look at the rev gauge when pressing the button, the needle will flutter then settle back to idle).
If this DOES happen then the problem is more likely to be mechanical (bad compressor, or a gas leak etc) as the air-con system is running.
If this DOES NOT happen then the air-con is not running because the vehicle's electrical system is not switching the air-con on when you press the button.
So to sum up, let the engine idle and press the button once to switch the air-con on, if you hear no "click/clunk" and the engines revs do not change at all you most likely have an electrical problem.
If you hear the clunk and see the revs change slightly (the needle will dip for a second) then you probably have a gas leak.

#21: Re: Got Air conditioning Re-gassed but still no cold air? Author: kandlbarrett, Location: SwindonPosted: Mon Jun 25, 2012 8:03 pm ---- You are already discovering that aircon is quite complex. Due to your limited knowledge i suggest that you take it to a specialist. I don't mean to be rude or arrogant but it will probably take many, many posts to lead you to the fault and that assumes you aren't going to need a multimeter to check supply voltages at various points in the aircon control system nor a leak.

i pressed the ac button when idle and dont see the revs changing or hear no noise but i see the ac light is on.
Please advise.
#23: Re: Got Air conditioning Re-gassed but still no cold air? Author: Deckchair5, Location: Bath UKPosted: Mon Jul 02, 2012 12:34 am ---- As stated above The system pressure safety switch will also stop the aircon compressor from cutting in if the gas pressure is to low OR to high.
So the first step would be to check system pressure whilst it is static to see if it at least up to the minimum. If you're unable to do that then you need to take it to an A/C specialist who knows what they're doing. If the pressure is not up to minimum then you have a leak and will need to take it to an A/C specialist. Your previous guy should have checked your A/C was functioning properly before handing the car back to you

Like I posted last week, take it to a aircon specialist that actually knows what there doing as your obviously out of your depth.

How can we tell, we cant see the car! Take it back if its not working, most places dont charge if it doesnt work.

these air con specialists will charge specialist money.
if i can get an idea of whats causing the problem then I dont have to go to a air con specialist and get the job done at a good reviews garage for fraction of the price.

Aircon check over including a service of the system is normally around £50 - £80 at a specialist.
Without the correct air con test equipment your stuffed.
Either pay up OR open the window.
You cant mess around with the gas side of an air con system, it can cause a lot of damage & even injury if you get it wrong!

that's a joke right? most garage don't have equipment to work on air-con and they will just ship your car to the air-con specialist to deal with it.
#30: Re: Got Air conditioning Re-gassed but still no cold air? Author: very_452001, Location: BirminghamPosted: Mon Jul 02, 2012 9:40 am ---- are the air con specialists available national across the country?
which is the best one to go with the good reviews?
