Hey all.

Its rather hard to determine if the aircon in my car works or not. In past cars with aircon, when I turn it on I often heard a whoosh sound, and after moments cool airflow, and a distinct smell that aircon air has over non aircon, however.

I put the dials to blow in face, right down to coldest air and blower on midway, and then turn on the aircon.

No whoosh sounds are heard, no change in scent of the air and it remains at the same temp as it is if I turn it off.

Can anyone give me a hint on what this could be. Is there anyway to find out if its simply a refill.

What I dont want to do is have it filled and find that was not the issue, cant afford to have that happen.

Thanks in advance.

Hi there, I know what you mean, I had a similar problem with the climate control on my Scorpio. I was also getting condensation on the windows (which gave it away as not working).

Normally, at idle, if you look at the rev counter, and switch on the air-con, you will see the revs momentarily fluctuate as the engine takes on the extra load, if that doesn't seem to occur, then the pump itself isn't activating. If it does fluctuate, then the system needs gas (and a leak fixed).

I had a mobile air-con engineer look at my car, and the problem was actually the fuse which controlled the pump. He also checked the gas & tested the system for leaks (thankfully all was fine). The total cost was £40 (which I thought was good value for money).

I would recommend that you get this looked at as soon as I did, as the gas itself acts as a lubricant for all the seals in the system - if its not being circulated, then the seals become porous, which makes the job more expensive yet.

Hope this helps,

Paul:)

It probably needs regassing from what your saying, they should be checked every 2 years ideally, and u should use your air con every month just to stop it getting clogged up.

U may also find if u set the air con to circulate round the car, the button you have, u wil find its colder as it just circulates the same air rather than having to cool new air, if you get me..

Air Con!

And don't forget to check the pollen filter - if its dirty airflow is reduced and the aircon is less effective.

hey all, sorry for the long delay, my job is killing me in early starts and late getting home, 5 hours a day sitting on the M25 really sucks.

Anyway. When I have the engine idling, and turn on the aircon there is no change in the revs state, suggesting the aircon is not coming on, gas or no gas. Can anyone help me work out where the fuze for this could be. Is there anyway this could be linked to my cig lighter not working as well (I doubt but you never know)

Couple other things.

After some tosser hit my car one night parked in the street, to my amazement, T-cut has removed all traces of the crash, lol, amazing stuff, appart from a couple of dents its good as new.

I think the arial connection on the roof is leaking, had a couple drips inside the other day after all the heavy rain, anyone know the best method to seal this up.


Under the lights, and above the main bumper at the front is a plastic piece that goes from one side to the other, the black grill piece appears to be clipped to it. I need to remove the plastic part (not the black grill) as the clear laquer is pealing, I have some new laquer spray to coat it, but have to remove it and clean it up. I found it unclipes from the sides, but not sure how the middle part comes away, brute force will likely bust it, anyone know?

Sounds to me like it wants re-gassing.....

Sometimes when the car's aircons not been used that much the gasses escape leaving your aircon now working poorly....

Just get is to a local reputable garage & get it topped up.....£45ish

I am a little concerned, money is rather tight right now, so I dont want to pay someone £45 to have it re-gassed, then find there is something else wrong, and more cost is incurred.

There must be a logical way to look at this.....

Button on, led status suggests its on, but no whoosh, no cold air, and the rev counter stays the same, so, I would think like so


  • Check fuze (where is the fuze...lol )
    Is there anyway to see if there is gas in the system
Surely there are ways to check such things without incurring a huge expense for no results.

Hi, Spotted haggis – the fuse is probably inside one of the fuse boxes and unless you have X-ray vision there is no sure way of telling if there is sufficient gas in the system (just like you can’t see how much gas is in the cooling system of your fridge). If you continue to run the system low on gas it will probably cause further damage. The companies that specialise in air-con recommend gas should be checked every two years or so. I appreciate you may be strapped for cash – so in the meantime it’s best not to use it at all. In regards to motoring costs £45 is not expensive nowadays - have a look around the forum and see what others are paying.:)

Kwik Fit

I had the aircon in my laguna regassed at Kwik Fit today. It costs £44.95.

They have a sign up saying if it doesn't work they won't charge you.


Hope this helps.

Brian.

just spoke to kwik fit slough, as i have the same problem air con not blowing cold,
£45 to re gas and if not 10% better no charge, worth the risk of £45 i guess

Also enquire at AA Auto Centre's Ex Halfords I get stuff (vouchers) come through from them every year offering free air con checks.
I have used this free check, they found nothing wrong. :d

Interestingly they gave me the vouchers back so I could pass them on to someone else.

hi, i have a laguna 1.9dti 2000 and have had it regassed and the ac still does not give me appreciable cool air. After about a month it gives no cool air at all. I noticed that the revs did not fall when ac was activated, therefore could you please tell me where i might find the fuse which contols the pump? or is it in the fuse box with the rest of them?

Thanks ghs

I am now in same situation. Air con was nice and cold for first 2 days after I got it regassed now nothing. Need to check the fuses and see if one has blown.

Just a thought -if the fuses to the pump don't resolve it - also worth checking for any corroded wires or connector blocks. That was the problem on mine - quite hard to access the wires, hopefully easier ona Laguna.

I have read quite a few threads on this forum relating to air con problems that seem in the main to point towards re charging - and/or power to the pump (fuses - bad connections)

I actually think if some of these issues are common e.g. corroded wires - they should become a service recall - anyway I don't know the frequency of this fault.

I read my handbook and it says if aircon is not cool check the fuses. I checked the list of fuses but none of them explicity say they are for the aircon. Can anyone tell me which fuse it is?

Thanks,
Brian.

If the cooling gradually got worse and then stopped all together , its the loss of coolant thats the problem. There is usually a pressure switch in the system which will only allow the pump to work if there is enough pressure in the system. As to the revs dropping when a/c is on - mine increases revs when the aircon is switched on - whether the aircon is working or not.(can be used as an indication that the control switch is working)
