A couple of days ago I noticed the car steaming up so I tried the aircon by setting it on cool, and it isn't blowing cold at all.

I thought, oh no it needs re-gassing, however a mechanic friend of mine pointed out that the compressor clutch is not engaging. We tested to voltage to the compressor with a multimeter and only achieved a reading of 3.2v not the 12v required (advised by Peugeot Doncaster).

I have checked all fuses both in engine bay and glove box and none are blown. Also I have had the car on PP2000 and tested the BSI and aircon ECU with no faults present.

I have read elsewhere on this forum that if the gas has leaked out then the system will detect this and not send voltage to the Compressor in order to activate the clutch mechanism, is this true?

Is there a relay hiding somewhere for the compressor?

Any help would be very much appreciated as I am reluctant to pay Peugeot dealer prices for them to scout around scratching their heads (as usual :D )

The clutch won't engage if the refrigerant pressure is too low. It's a safety measure to pretect the compressor.

The 407 aircon has proven generally very robust, with a few begining to need repressurising due to age and/or lack of use. Check the obvious before worrying further, ie, get the refrigerant pressure checked and topped up if required. Kwik Fit are cheap for this.

As chopper said, clutch wont engage if pressure is too low so a leak test/top up is definately reccomended

And again chopper hits nail on the head, its one of the few things kwik fit are good for so i'd head there! :thumb:

when i took mine there for a refill they found a leak, no charge for this diagnosis, fixed it myself and took it back for a top up, sweet as a nut it is now!

All sorted... The pipe from compressor to condensor was perished. New pipe from peugeot and a re gas did the trick. Got to change the pollen filter now, any ideas where it is?

Undo the clips holding the carpet trim udnerneath the glovebox and you'll see it. It's in the plastic cannister up and towards the right. Unclip then end and pull the old filter out. The new one will be a bugger to ease in without bending or squashing it and takes some patience.

308 a/c faulty.

Hi. I'm not sure if I have the same problem? My air con wasn't blowing cold so had the system re-gassed. Shortly after, it was just as bad as it was before it was re-gassed. I did notice, when the A/C button was pressed (my car has climate control) there was a faint noise coming from the 'system' or possibly the compressor.

I took the car back to the garage who re-gassed it and they say I needed a new compressor at about £600 which I simply cannot afford!!! :mad:

After talking briefly to an A/C specialist he suggested it might not need a new compressor. :confused:

Have you got any thoughts on my next move? I'm liking the idea that a test with Kwik Fit could help? I'm not near the A/C specialist at the moment.

Thanks in advance

Jon
